How to choose an engraver - a complete and comprehensive guide. Electric engravers: which one is better to choose? Disadvantages noted by users themselves

An engraver, also called a mini-drill, dremel, straight grinder or drill, is a multifunctional tool. With its help, not only engraving is applied, but also drilling, grinding and performing other operations for processing various materials, for example, wood, metal, glass, stone. The device is widely used both in everyday life and in various industries industry, in jewelry, when creating advertising and souvenir products. All the variety of functionality of the equipment is due to the fact that there are different attachments for the engraver.

Attachments for frequently performed types of work are supplied complete with the tool. Milling cutters for more specific operations must be purchased separately. In order to work correctly and efficiently with a Dremel, while achieving high quality processing of parts, you need to know existing varieties equipment, as well as for what work each type is used.

Exists a large number of varieties of equipment for working with a mini-drill. A wide range of on the market allows you to select attachments for wood and many other materials that engraving equipment can work with. Also, individual craftsmen make them themselves.

Structurally, the attachments (burs) consist of two parts;

• tail, clamped in the tool chuck (diameter from 0.8 to 8 mm);
• worker who processes materials.

Equipment is classified according to two main criteria:

• by the type of material from which they are made;
• by area of ​​use (purpose).

By type of material processed

Based on the material, engraver cutters are of the following types.

There are also combination burs that have a steel shank and a carbide working part. Their area of ​​application corresponds to the material of the head.

Carbide equipment is of high quality, durable and is one of the most expensive consumables for Dremels. The shape of the tips determines the features of its application. With the help of such peak burs, it is good to process bone, plastic, and make tracing (indicate the contours of the picture). Diamond bits They are also distinguished by their quality, even if the kit they are included in is classified as cheap consumables.

On the market you can find a set of burrs, all the elements of which marked with any color– it indicates the level of sharpening. Those marked black are the most productive burs, while the sharpness of green or blue ones is worse. Labeled yellow nozzles are the optimal choice when performing finishing blanks

By purpose

You can use an engraver with attachments not only for engraving, but also for performing other work operations. The breakdown of consumables used in the operation of straight grinders is presented in the table below.

Consumables from each group can be used when processing various materials. Wherein milling equipment used mainly by professionals.

Dremels, which have a flexible shaft installed, are equipped with any types of consumables that fit the diameter of the tool chuck.

Diamond burs for engraving

Diamond burs rightfully hold the title of the most popular attachments for engravers. They are included in professional configurations these tools. The tool is strong and durable if used correctly.

The bur itself is made of tool steel. Dust from small industrial diamonds is applied to its surface. They are the ones who cope with such durable materials as glass and ceramics. Diamond burs can be used to process semi-precious stones, natural and artificial. They handle metals and alloys with ease.

Burs of this type are not used for roughing; their purpose is to refine shaped grooves and holes. Nozzles are most often sold in sets. There can be 10-20 of them, different in shape. To produce fine work, craftsmen can find diamond bur professional grade and buy it in one copy.

Set of diamond bits for engraver

In order for a tool to serve for a long time, it must be operated according to a whole set of rules. Manufacturers usually give clear recommendations about what can and cannot be done with their diamond burs.

Abrasive attachments

As the name implies, this class of tool is designed for grinding or rough removal of a layer of material of small thickness. Usually a set of abrasives is supplied with engravers. There can be from 3 to 6 pieces, shank size 2.3 mm, with different shapes of the working part.

Abrasive attachments allow you to:

• roughly grind areas of parts (without polishing);
• process holes, including for boring purposes;
• perform engraving work.

Tools of this type are quite rough. The results of their work are difficult to control. Therefore they most often used in everyday life, home workshops for operations without strict quality requirements. Professionals high level This type of tool is rarely used.

In the design, except for the steel rod - rubber mixture, to which various abrasive particles are added. It can be aluminum oxide or diamond chips. Abrasive attachments are used for working on metal, ceramics, glass, and other materials.

Some manufacturers add dyes to the body of the instrument, indicating the optimal scope of application. For example, a red product is made with the addition of aluminum oxide. It works well on metal surfaces.

The area of ​​application depends on the color of the nozzle

Green attachments are designed for engraving stone and ceramics. It is acceptable when working with glass. The composition of the body of such an attachment silicon carbide. Like other general class products, painted ones are offered in different forms, standard sizes.

Grinding and polishing attachments

Typically the polishing pad is made of felt. In itself, it is not a working tool. It's just a device that is applied to grinding paste. However, attachments play an important role. Available in different shapes and sizes, they allow optimal processing of curved surfaces.

The choice of paste depends on the tasks facing the operator. A distinction is made between grinding and polishing. The type of paste chosen depends on the target material for processing; it can be wood, metal, glass, plastic, and so on.

1. It is best to work with metals, even of high hardness paraffin-containing pastes. They add an extremely fine fraction of a special abrasive powder.
2. Sweeps work well on glass based on diamond dust, capable of bringing the surface to an ideal state.
3. Wood can also be treated with pastes containing diamond dust. Best choice will become a mixture containing abrasive fractions of 3/2, 5/3.

Diamond polishing paste

Scope of application polishing attachments are very wide. They are used by home craftsmen working in the most simple tool. Widely used in the jewelry industry. They work in dental clinics and denture manufacturing companies.

Review of professional attachments for engravers

Professional tools constitute a separate (high-quality and expensive) category of equipment that can withstand without negative consequences significant operating loads. Such devices are usually equipped with appropriate consumables.

Professionals process the smallest details of workpieces with high quality. That's why they need such a wide variety of consumables to get the job done.

Experts who engrave various materials professionally recommend purchasing sets of attachments from well-known brands, such as "Dremel" or "Dexter". The significant cost of products from these companies is fully justified by the fact that their products are reliable, high quality and durability. The use of burrs for wood, metal and other materials produced by these companies increases the accuracy of workpiece processing.

Often, specialists have several sets of equipment designed to process different materials and perform various operations. Also, the individual elements that make up them have their own design features. Typically these sets include:

• cutters for metal, wood and other materials, of various designs;
• drill;
• felt, diamond, and abrasive cutters;
• wire brushes for cleaning surfaces;
• engraving rods;
• cutting discs.

The kits also include a straight edge cutter.

Straight edge cutter Topfix

Replacement equipment of the Dremel and Dexter brands can be used not only by workshop specialists, but also by home craftsmen who want to improve in the art of engraving.

According to professionals, one such tool can last as long as 10 low-quality attachments from an unknown manufacturer.

Some engraving artists recommend products "Zubr" company, lower quality than Dremel or Dexter, but cheaper. The set can include up to 180 units of consumables of popular varieties. But products from Zubr, in general, fall into the semi-professional and household categories.

Typically, a milling attachment for an engraver is included with the purchased tool. But with constant use, it wears out over time. Also, cutters may be needed for specific operations - then you need to buy new burs in order to continue working with the Dremel.

The ideal option is to purchase products recommended by the engraver manufacturer. In such cases, the warranty from the companies for the device in use is retained. But it happens that original consumables cannot be obtained for some reason, or they will be very expensive given the small volume of upcoming work operations. Then you will need to purchase analogues or even use homemade ones. In this case, the main rules of choice are as follows.

1. You should focus on a Dremel chuck that fits shank diameter: most often it is 2.4 or 3.2 mm.
2. You need to purchase attachments for metal and other materials depending on the type of work you plan to perform.
3. To engrave, you can use inexpensive sets, for example, Chinese or Russian production.
4. For constant, long-term work with a mini-drill (especially with hard materials), it is recommended to purchase high-quality, professional sets, and for occasional engraving, household ones are sufficient.

When learning various Dremel operations, inexpensive products are suitable. Over time, they should be abandoned in favor of better quality equipment.

Homemade attachments for the engraver

You can buy attachments for the engraver not only factory-made, but also make them yourself. Workshop specialists and home craftsmen have come up with many options that are suitable for performing various operations with different materials.

To make your own polishing, grinding, milling, drilling consumables for a Dremel, as well as cutting devices, use the following materials and parts:

• plywood;
• sandpaper;
• remnants of abrasive wheels of different thicknesses from an angle grinder (grinder);
• felt;
• felt;
• various fabrics and rubber;
• steel wire;
• a wheel from a cheap lighter;
• old burs and drills (they are sharpened);
• electric razor knives;
• hacksaw blades;
• metal caps, for example, from beer bottles;
• champagne corks;
• an ordinary dowel (its head has teeth) and others.

The photos below show some ready-to-go practical application homemade devices to a milling type engraving device.

Additionally used with homemade products special (for example, diamond) pastes. At the same time, specialists achieve the result of finishing processing of workpieces of different densities, comparable in quality to the use of factory analogue burs.

Homemade engraver attachments are suitable for performing a variety of jobs in domestic conditions. They will also save money through the use of available, cheap materials and parts from improvised or broken (unnecessary, old) mechanisms.

A wide variety of different attachments allows you to use a Dremel to perform a wide range of different jobs with different materials. It is better to select consumables that comply with the recommendations of equipment manufacturers. Professional kits- This is a guarantee of product quality, but they are expensive. To save money, you can make the necessary devices yourself. Just keep in mind that in this case the warranty service for the mini-drill is lost, and during operation the load on the tool may increase.

If you need to do fine processing of metal or wood, or draw a pattern on stone or glass, then use an engraver. It performs the functions of a drill, grinder, milling machine, but on a very small scale. Therefore, it is also called a mini-drill and drill. Which device to choose for the job, how to maintain electrical equipment and repair it if necessary?

Purpose and types of engravers

The engraver is compact electric tool, which are processed various materials: wood, stone, glass, metal. The device performs not only drawings and inscriptions on the surface. This versatile tool can be used for grinding, milling, engraving, cutting and drilling. Such a difference in the number of operations performed is possible thanks to interchangeable nozzles. The engraver is used where precise, accurate work is required. This includes jewelry and watchmaking, polishing in narrow openings, design, decor, modeling.

to his appearance the engraver reminds directly grinder. Main elements: motor, gearbox, spindle, housing. Nozzles are inserted into the spindle. Pressing the button starts the engine. Its rotational motion is transmitted to the gearbox, and then to the spindle, which rotates the nozzle.

The following types of engravers are distinguished:

• battery-powered They do not connect directly to the network. Used away from outlets;
• electric. They work only from the network;
• with flexible shaft. This is a hose of various lengths with a cable inside. The shaft is installed between the spindle and the nozzle. It acts as an extension cord. It is convenient to work with such a shaft, since it is lighter than the engraver, which weighs about a kilogram. It can be held in your hand like a pencil. Very convenient when making drawings, inscriptions, decorative processing;
• laser These devices are machines. They are tabletop and floor-mounted. The latter have large dimensions and are used in production. Based on the type of laser, engraving machines are divided into the following types:
  • gas. Process all materials: from leather to metal;
  • solid state Used to work with metal and plastic. This device is used to mark products, write symbols on a computer keyboard, and make inscriptions.

Photo gallery: what types of devices exist

The cordless engraver has a built-in battery and is used away from electrical outlets
Electric engraver without battery, but with mains cable. It works only from the mains. An engraver with a flexible shaft has a flexible shaft installed between the spindle and the collet, which acts as an extension. The gas engraver has big sizes and used in production
A solid-state engraver is much smaller than a gas engraver. It is installed on the table, used in everyday life and small business

Classification of engravers according to the material processed:

• on metal. Used to work with hard materials: metal, stone, glass;
• on wood. For processing wood and thin plywood.

How to choose an electrical appliance

To avoid making a mistake with your purchase, determine two things: what kind of work you need the tool for and the type of workpiece material. Then analyze the following selection criteria:

• electric engraver or battery. Consider whether you need an outlet nearby;
• The main parameter of the tool is power. The greater the value of this characteristic, the better quality tool will complete the task and process hard materials better;
• the second parameter is important for selecting accessories. This is the collet size. It is designed to clamp and hold engraver attachments. The most common collet diameter is 3.2 mm. Minimum - 0.8 mm. If you find collets of several sizes in the kit, then this is a big plus. Since you will have the opportunity to use a wide variety of attachments;
• number of revolutions and the possibility of their adjustment. This is a very important parameter because there are attachments that cannot be used at low or high speed. Therefore, engravers with a large maximum number of revolutions and the ability to adjust them are preferable. Since they can use various attachments, which means they can perform a wide range of work;
• tool weight. It is advisable to choose a lightweight engraver because the work of making patterns and polishing takes a lot of time. Holding a heavy instrument in your hands for a long time is quite uncomfortable.
• When choosing a tool, considerable attention should be paid to the configuration:
  • The presence of a flexible shaft in the kit will save you from the need to purchase it separately. The flexible shaft itself is very useful and increases ease of use. You can hang the tool on a hook and take the flexible shaft by hand and work;
  • presence various attachments will also be a plus. There is a complete set with a whole suitcase of accessories. You may not need some at first, but later you will already know what you need. And don't waste money on the right attachment;
  • packaging matters. It would be good if it was a high-quality case that would hold the engraver with all the accessories.

I bought an engraver Leroy Merlin DM-130 for minor works, where great efforts and high speeds are not needed. End and front grinding wheels, circular abrasives of different sizes, drills, engraving attachments, GOI paste, cutting wheels (a thing!!!) of different thicknesses, metal brushes!... And everything seems to cling well, inserted, pressed and fastened! It works a little loudly, but does not vibrate, and this is valuable for those who plan to make inscriptions on metal. The revolutions are regulated by a “wheel”-regulator in the “plus and minus” direction. I liked the device for its cross-country ability and unpretentiousness.

I purchased the engraver Diold MED-2 MF not for professional work, but, let’s say, for the home. I was very pleased with the price for the set - 2700 rubles, as well as the rich set (indeed, a lot of things are included in the set). If you use it often, it won’t be very convenient to pack everything back into the case. Among the shortcomings, I can note the lack of a tripod stand. Not a particularly informative instruction (you can figure it out without it, but an unprepared person may still have problems). The kit comes with polishing paste in a tube, but how to get it out of there is still a mystery)) The standard polishing disc (something like felt) was turned after about 2-3 minutes of work (I don’t know how long they last on other engravers, Well, maybe it’s his own fault - he pressed hard...). In terms of the rest, there are probably no complaints. Although among the replacement cutting wheels there was one cracked one. It took me a while to figure out how to screw on the flexible shaft. and so far the impressions have been only positive. For my money I definitely recommend it! Obviously the Chinese will be better.

How to work with it: correct operation

To avoid damaging the product when operating the device, you need to know the rules of use and safety precautions.

Preparing the workplace and tools

1. Designate a table with free space.
2. Install a powerful lamp so that all the small details can be seen.
3. Cover the work surface with paper or cloth. Dust and chips are generated during cutting and grinding.
4. Stock up on carpenter's tape, a pencil or a felt-tip pen for drawing. Scotch tape is needed to secure the draft to the surface. The paper tape is easy to peel off and leaves no marks. To apply patterns on a metal, plastic or glass workpiece, degrease the surface with alcohol so that the felt-tip pen does not wash off. Apply the initial drawing on the wood with a pencil.
5. Prepare all necessary attachments. To do this, read the instructions for the device. There is a description of the purpose of all consumables.
6. If you bought an engraver complete with a suspension, then install it in a convenient place. It helps eliminate vibrations during operation and reduce errors. When installing the gimbal, be guided by the placement of the flexible shaft. He shouldn't get in the way.

How to use

1. Wear fabric gloves so that the hand with the tool can easily glide over the surface of the workpiece and stains will not appear on the product.
2. If you are a beginner, select minimum number rpm Then the pattern will be even, the strokes will be of the same depth, and the material will not be damaged. Turn on the engraver.
3. Trace the outline of the drawing. Once completed, move on to drawing small details.
4. When the pattern is completed, use a soft felt attachment. It usually comes complete with the engraver. This equipment removes roughness.

Safety precautions

• check integrity before work network cable and work items;
• use safety glasses to prevent sparks and dust from getting into your eyes;
• To drill and cut materials, hold the device firmly with your entire hand. This way you will avoid arbitrary movements, damage to your hands and working material;
• If the equipment is jammed, do not pull it out of the workpiece. First unplug the engraver or remove the battery. Then remove the nozzle;
• If the engraver body heats up, turn it off and wait until it cools down. If the device does not have a cooling system, then it will have to be interrupted often. This way, you will avoid engine overheating. The instructions describe the operating time;
• When purchasing consumables separately, make sure they match your instrument. They must have right size shank and match the speed of the engraver.

Care

In order for the tool to work fully for many years, it is necessary to monitor the condition of the working equipment. If visual inspection of the attachments reveals various damages, replace them with others of the same brand as the engraver itself. This is the only way the tool manufacturer can guarantee the device’s operating efficiency and long service life.

After each cycle, clean the ventilation holes in the housing. With their help, the engine is additionally cooled. But when processing wooden, plastic or glass workpieces, the holes become clogged with dust. The resulting contaminants affect the performance of the tool and cause its failure. To avoid this nuisance, you need to remove debris carefully using a damp, clean rag. It can be soaked in soapy water. To avoid damage to the housing, do not use products based on alcohol, thinner or gasoline. The equipment that was used in the process also needs to be cleaned.

Sticking to these simple tips, You will for a long time use an engraver and get high-quality results.

DIY engraver

The device can be made from the simplest available materials.

Electric pencil

This method is only suitable for engraving on conductive surfaces. The core of a simple stationery pencil consists of graphite, which transmits well electricity. You can use an electric pencil to engrave on metal surface. Such a pattern can only be erased with a grinding machine. You will need: a pencil with an eraser at the end, a plug for a socket with a two-wire cable, a 100 W light bulb, rubber gloves, two pieces of wire, an alligator clip, a metal blank, such as a knife.

1. Remove the eraser from the pencil and drill it through the middle.
2. Pass the wire through the hole. Remove a few centimeters of insulation and twist the exposed area. Sharpen the pencil slightly where the eraser was to improve contact.
3. Place the eraser with the wire on the pencil.
4. Take the lamp. Connect a pencil to one terminal and the core of the plug cable to the other. Connect the unused wire to the crocodile and to the free wire of the plug. Connect the metal clamp to the knife. The structure is ready.
5. In order not to spoil the workpiece with an accidental blot, first apply a rough inscription. Wear rubber gloves for safety. Plug your device into the network and start working. During engraving, a spark is formed between the pencil and the knife, which creates the design.

Universal engraver

Using this option, you will be able to perform different operations. You will need: a power supply connector with two wires, a button, a plastic bottle with a cap, a 12V power supply, a 12V motor, a piece plastic pipe 10 cm long with internal diameter slightly larger than the engine.

1. Drill a hole in the pipe for the switch. Coat the motor casing with hot glue to secure it to the pipe.
2. Insert the motor into the pipe. Pass one of the wires through the hole.
3. Insert one wire of the connector for the power supply into the pipe and pass through the hole. Take the button. Solder two wires sticking out of the hole to it. Insulate the contacts.
4. You should have two free wires left: from the engine and from the connector for the power supply. Connect them.
5. Cut from plastic bottle part of the neck with a lid. Drill a hole in the center of the cover for the connector. Glue the connector to the cover and the cover to the pipe.
6. Take a 12 V power supply and connect it to the connector. Press the button to check the engine's functionality.

Instead of the connector for the power supply, you can install a pair of batteries.

Repair of engraver and consumables

The main malfunctions of the engraver and their causes:

• the engraver does not turn on. You need to charge the battery if available. And turn it on again. If the problem persists, check all wires and the motor with a multimeter;
• doesn't turn. The reason is the power button or the motor;
• spins weakly. Not enough power. Check the brushes;
• rustles or crunches. The reason is the gearbox or bearings;
• sparks or gets hot. The engine is faulty.

Analysis and troubleshooting

To identify and correct problems, the tool must be disassembled.

Video: how to disassemble and check the device for damage

Repair of collet and flexible shaft

If the collet no longer clamps the nozzles, you need to unscrew the clamping tip and remove the collet. A broken part cannot be repaired, and blockages between the petals must be removed regularly with a thin, sharp object. They interfere with the full clamping of the attachments.

The flexible shaft is a hose with a cable inside. The cable must be lubricated with graphite lubricant. To do this, bend the shaft and the cable will come out through the sleeve. Pull it out and lubricate it.

If the cable is broken, it must be replaced.

Selecting and replacing attachments

When choosing accessories, consider the collet diameter of your tool. If necessary, buy a set of collets of different sizes.

Types of nozzles:

• carbide. WITH different types notches. They have large and small heads. Designed for pre-treatment or intermediate operations;
• diamond Made of diamond coated steel. Very productive. This is the main working tool;
• disk holders. Cutting, rubber, and felt wheels are installed on them;
• rubber with corundum. For metal processing;
• abrasive. For processing ceramics, stone, glass, metal;
• felt For polishing wood.

How to replace the nozzle

You need to loosen the collet, remove the attachment, insert another one and tighten the collet. To install the flexible shaft, the collet must be removed. Install the rectangular adapter, and put the flexible shaft sleeve on it. Screw a collet onto the working end of the shaft.

How to make your own nozzles

Having an engraver on the farm allows you to perform a wide variety of operations. And it’s not at all necessary to draw patterns or drill holes in printed circuit boards. An engraver will help you simply remove rust from a bolt or coupling. It is much more difficult to do this with sandpaper or a grinder. And if you don’t want to spend money on a device, you can assemble it yourself. Such a tool will be easier to repair. Replaced the engine or worn out homemade nozzle and the problem is solved.

Most men love to tinker with iron and wood, drilling, hammering, screwing and screwing, doing useful things around the house or garage. Even one nailed shelf or twisted socket fills us with self-esteem and calm confidence in our abilities. But it’s not always possible to keep a set of tools at home sufficient to carry out a variety of household chores. You have to borrow either a screwdriver, or a grinder, or a grinder. And so it was until the engraver appeared - a universal tool that allows you to carry out a lot of precise work on grinding, drilling, engraving and cutting, and does not take up almost any space.

What is an engraver?

An engraver, or mini-drill as it is sometimes called, looks like a huge pen with a network connection. If we open the housing, we will see that it consists of a motor, a spindle, a gearbox, and an impeller, which cools the motor itself. The case has holes for hot air exhaust, as well as a place for holding (some models have removable handle), an on/off button, a button that blocks the motor, a nut for fixing various attachments, and a cord for connecting to the network. Most often, the engraver is equipped with an additional ring for hanging on a special tripod. For some models, removable ones are available for working in hard-to-reach places, for example, in a car or under a sink - such devices are equipped with a Dremel engraver and other expensive mini-drills.

How does he work

The device works due to the fact that the engine spins the shaft (from 3-4 to 35-40 thousand revolutions - Dremel engraver and similar), thus rotating the attachments attached to it. It is the wide range of attachments used that forms the versatility of this tool - from a drill it turns into a grinder, and then into an angle grinder. And all this fits into one small box.

Of course, the engraver is significantly inferior in power to its “big brothers”, and it is hardly appropriate to drill walls with it, as well as cut metal sheets, but such a task is not faced with it. Plumbing work, home repairs, minor preventive maintenance and car repairs, engraving, finishing of metal and wooden products- the engraver copes with all this perfectly.

How to choose an engraver?

First of all, you need to determine the range of tasks that this tool should solve. Would you like to polish your home gold once a month? Or work with him in the workshop from morning to evening? Depending on this, you should choose your assistant:

1. Power. Typically ranges from 30 to 300 W. The higher the power, the greater the range of materials you can work with. Engine life, operating time with the engraver at one time - all this depends on the power parameter. As a rule, household engravers are rarely more powerful than 100-150 W (this includes an engraver, and professional ones, in turn, are 175-200 W (engraver
2. Weight. If there is no need for a powerful, super-efficient engraver, then you should not buy models weighing more than a kilogram, because working with such a tool will become very difficult and tedious. Lightweight and productive mini-drills include, first of all, the Dremel engraver.
3. Ergonomics. The engraver should not only work well, but also fit comfortably in your hand - otherwise you will spend half your working time on finger exercises. The same goes for weight distribution - the closer the center of gravity is to your fingers, the easier it will be for you to work.
4. Noise, vibration, heat. Everything here is quite simple - the more expensive the device, the fewer problems it creates. In elite models, these problems are solved with a good margin of safety - which is also why they have such a high price tag. Cheap models regularly suffer from overheating, they are characterized by manufacturer defects, but they make a little noise - rather weak. But mid-priced engravers can get hot, vibrate and make noise - they have enough power, but manufacturers turn a blind eye to minor inconveniences.
5. Equipment. Almost every engraver is equipped with a set of attachments. Its completeness depends on many factors, but in most cases, experienced users buy additional attachments - either as a set or separately. Even with the most careful use, the attachments are consumables, and from time to time they will have to be purchased.

Which company should I buy an engraver from?

There are a number of manufacturers on the market that produce engravers - Hammer, Makita, Hitachi, Sturm. The most popular and widespread is the Dremel engraver. The tools of this company have become so famous that they are used as the name of all similar devices - “engraver” and “Dremel” can be heard equally often.

In any case, you should choose an engraver after carefully reading consumer opinions about a particular model. And the Dremel engraver deserves only positive reviews: tens of thousands of users give the highest ratings to the line of these tools. And you shouldn’t, of course, focus on Chinese analogues- It’s better not to skimp on hand-held power tools.

An electric engraver, or drill, is a compact tool designed for engraving and fine processing of various materials. This equipment is produced by both branded European manufacturers and little-known Chinese brands. In this regard, the range presented on the market differs in price and quality. Engravers come in different sizes and power, so you can choose the optimal equipment to perform the amount of work you are interested in.

What can an engraver do?

Hand engravers are compact equipment that is used for precision machining. In this regard, it cannot be used to implement global tasks.

Engravers are equipped with various attachments, which makes it possible to use them for the following types of work:

• Grinding.
• Milling.
• Engraving.
• Cutting.
• Drilling.
• Polishing.

The device is compatible with small nozzles, so its use for construction or large-scale tasks is unacceptable. If you load the engraver, say for drilling thick-walled steel, the device will simply burn out. The electric motor installed in it is not designed for heavy loads, so it can stop if the resistance of the material being processed is high.

Principle of operation

According to the principle of operation, engravers are similar to a regular drill, grinder or screwdriver. They have a lightweight body in which an electric motor is installed. A collet is attached to its shaft, with the help of which the attachments for processing are fixed. The engine can transmit power with or without a gearbox. The tool has engine speed adjustment. Some models can rotate in both directions.

The vast majority of commercially available engravers provide rotating attachments, but there is a separate category of impact devices. Such a tool does not drill into the surface of the material, but hits it with a sharp tip of the nozzle. Such equipment is highly specialized. It is intended exclusively for engraving on hard surfaces. Since the spindle does not rotate, cutting, polishing or grinding workpieces with such equipment will not be possible.

Types of engravers

According to the method of execution, hand engravers can be divided into several types:

• Regular network ones.
• Rechargeable.
• Hanging.

Conventional network engravers

A conventional network engraver is a device that is held in the hand like ballpoint pen. The tool is connected to the electrical network. This engraver can be supplied with a flexible shaft. It is fixed in the main collet of the tool, and has a miniature chuck at its tip. Thus, you can place the drill on the table and hold only the tip of the flexible shaft in your hand, providing fine processing. This allows you to reduce the strain on your hands if you are doing a large amount of work.

Often, low-price tools come with a flexible shaft, which quickly breaks down. When periodically bent, it breaks or jams. As a result, the electric motor inside the engraver body stops. If it is not turned off in time, the tool may burn out. In this regard, even if you choose a cheap tool, you should avoid using the included flexible shafts. The optimal solution There will be a purchase of a separate shaft produced by a name brand.

Electric engravers are available in various sizes. On sale you can even find miniature devices that have low power. They are very light and compact, but their performance is only sufficient for precision machining soft materials. Such equipment is chosen for modeling.

Mobile cordless drills

Cordless engravers are more expensive than networked ones, but they are practically no different from them. Their only feature is that they have their own power source, so if the battery is charged, you can work anywhere without being tied to an outlet. To recharge the battery, the kit includes both a regular charger and an adapter for installation in the car's cigarette lighter.

There are even engravers on sale that run on regular AA batteries. Of course, their productivity is very low, but such tools have found their application. They are bought for polishing jewelry and other delicate and very light work. These Chinese engravers are the cheapest, and in most cases are useless, since they can only perform the simplest tasks.

Hanging engravers

The suspended type of engravers deserves special attention. They have a square or short cylindrical body that can be hung on a wall or countertop. From it comes a flexible shaft, similar to that used on conventional network devices. A pedal is installed between the housing and the wire for connecting to the socket. It fits under the operator's feet. When working with such a tool, you need to press the pedal with your foot, after which power is supplied to the electric motor, which rotates the nozzle installed in the collet on the shaft.

The pendant engraver is convenient because the flexible shaft is made of high quality, it is lightweight and fits comfortably in the hand. If the work is finished, you just need to release the pedal with your foot. This reduces operating noise. If you need to pause for a few seconds to review your results, you can easily turn off the tool, thereby stopping the noise.

Engraver selection criteria

The engraver is quite a popular tool, so it is not surprising that dozens of brands are engaged in its production. In this regard, there are many models on the market, which complicates the choice. If you want to purchase such a tool, you should be guided by the following criteria:

• Power.
• Number of revolutions.
• Noise level.
• Collet size.

The first criterion is power. It depends on it how productive the tool will be. If the engine is too weak, then any attachment in contact with the material being processed will reduce its speed, after which the shaft will stop completely. As a result, even the simplest tasks will take a long time to complete instead of just a few seconds.

For home use It is worth choosing equipment with a motor power in the range of 120-170 W. A tool with such characteristics will not only be able to perform quick engraving, but, if necessary, will allow you to drill a small hole in the metal or trim some workpiece. If an engraver is needed for a hobby, in particular for processing miniature wooden parts, modeling, then you can get by with a 35-50 W tool, although it is rather weak. The more powerful the tool, the better, but this increases the cost of the equipment.

As for the number of revolutions, for comfortable operation, devices with an engine rotation of over 20 thousand revolutions are usually chosen. Name brand tools, even with a 170 W motor, often produce up to 32 thousand revolutions, so the figure of 20 thousand is modest. The simplest hobby engravers can produce 6-8 thousand revolutions. Most of the tools on the market have smooth adjustment, which allows you to adjust the engine rotation from a safe minimum to maximum.

The tool that will be held in the hands should weigh between 500-750 grams. If you have the opportunity to purchase a powerful, but at the same time lightweight engraver, then you should give preference to it. A drill that is too heavy will quickly tire your hands, so if you need to work for a long time, it will not be suitable. If you plan to use a flexible shaft, then the weight criterion is not critical.

When working in a residential area, you should give preference to low-noise devices. In addition to the noise that the electric motor creates when rotating, the sound of the nozzle rubbing against the surface of the material being processed is also added. If both sound sources are loud, then it will be unpleasant for other residents to be in the apartment or house. Even a noisy tool can be chosen for work in the workshop if the operator plans to use headphones to protect his hearing.

The last, but one of the most important criteria is the size of the collet. The name of its parameters determines which attachments can be clamped in the tool. The most common option is collets with a diameter of 3.2 mm. They are most often used both in everyday life and in professional processing. It is ideal if the tool comes with several collets that can be installed on the spindle extending from the motor. In addition to the 3.2 mm diameter, 2.4 mm, 1.6 mm and 0.8 mm collets are also common.

Engraver equipment

Engravers are sold in a specific configuration. The cheapest tool is offered simply in cardboard box, and has nothing except the engraver himself. Sometimes the basic set can be expanded, which is found in more expensive assortments. In this case, the package may include:

• Flexible shaft.
• Angle adapter.
• Hanging stand.
• Storage case.
• Box with nozzles.
• Spare graphite brushes for the engine.
• Templates with letters for engraving.
• Collets of various diameters.

Most often, the kit contains just an engraver with several attachments and collets. As for the angle adapter, stand and flexible shaft, they are less common. A plastic storage case is included with equipment in the higher price segment. It is worth noting that those attachments that can be found in the standard configuration leave much to be desired in terms of wear resistance. They wear out quickly, so you will soon need to buy new ones.

Working as an engraver is a fascinating procedure with which you can create various patterns and inscriptions on the surface of the workpiece, grind and polish small parts, and also solve a whole list of other tasks. In order for the results of working as an engraver, which can be a standard drill, to be of high quality, it is necessary not only to understand why it is needed, but also to know all the nuances of using such equipment.

The engraver allows you to work not only with wood, but also with other materials

Equipment selection

When choosing an engraver or drill, you must decide for what work such a device will be used, as well as what materials will be processed with its help. Knowing this, you can choose an engraving machine for working on metal and other materials or a drill for wood carving (even taking into account the huge variety of similar devices presented on the modern market) without any problems.

Most significant characteristics The engravers you should focus on are:

• power of the drive motor, which determines the ability of the equipment long time work under significant mechanical loads and process various materials;
• the number of revolutions developed by the working body in which the engraving tool is fixed.

Nowadays, there is plenty to choose from; each manufacturer produces several models of engravers that differ in both price and functionality.

Very often, those who are planning to purchase an engraver for their professional activity or for work at home, you have to make a choice between the two characteristics mentioned above. No matter how much one would like it, not a single modern engraving device from among serial models is capable of effectively combining high power and speed. That is why specialists who often have to use an engraver immediately purchase both powerful and resourceful models. Optimal choice in such cases will become:

• powerful engraver, the working tip of which has a reinforced design;
• compact and lightweight micromotor capable of operating at high speeds.

For heavy work, a tool with an additional handle will be convenient, and fine engraving is best done with a compact device

For not too complicated engraving work at home, you can make such a device yourself, giving it exactly the functionality and characteristics that are necessary. There is a wide variety of designs of homemade engravers and videos about their manufacture, so choosing an acceptable option is not difficult. For example, you can make an engraver that will be driven by an electric motor from an old household appliances. However, to make it convenient to work with, a homemade engraving machine must be equipped with a flexible drive and a special attachment in which the tool used will be fixed.

Using a homemade engraver at home, you can not only apply inscriptions and patterns to the product, but also perform different kinds processing parts made of metal, plastic and bone. Wood carving with a handmade engraver is also possible. Depending on the working tool installed in the attachment of such a device, it can be used as a mini-drill, a small router, a compact grinder and polisher.

To choose production model An engraver who will effectively cope with all the assigned tasks should be guided not only by the rating of such equipment among specialists, but also by its characteristics and functionality.

Serial models of engravers

Serial models of engravers, which are equally successfully used both at home and in the professional sphere, can be divided into the following categories.

These are powerful sleeveless devices with which you can successfully perform various technological operations, namely: drilling, grinding, milling, etc. Such units, operating at low speeds, are equipped with a convenient foot pedal and can be used in conjunction with both collet and quick-release chucks.

The power of technical drills allows them to be used for various operations with the help of additional attachments and accessories

The compact drive motor that is equipped with this type of engraver is mounted at the rear of the working attachment. Such small and high-speed engravers, not intended for heavy loads, are used primarily for the most delicate work. At the same time, the micromotor with which these engravers are equipped cannot be repaired; it can only be replaced with a new one. That is why it is advisable to use these devices for not too complex work, without subjecting it to significant loads.

These drills are very convenient to use for engraving and fine carving. However, it should be borne in mind that the flexible shaft with which they are equipped reduces their power by almost half.

How to work as an engraver

To make the work performed by the engraver more comfortable and efficient, certain rules should be followed.

The working surface on which engraving is carried out with a drill must be well lit, so it must be equipped with a powerful lamp that allows you to easily examine in great detail all the elements being processed. If used for engraving paper template, then you will need masking tape, with which the template is fixed on the surface to be treated. Sometimes a sketch of a design or inscription that needs to be engraved is applied to the product being processed with a regular felt-tip pen or pencil. The surface must be degreased with alcohol.

To perform engraving, use various instruments, installed in the engraver. Each of them performs certain functions. Thus, a tool with a cone-shaped working part is needed to apply the outline of a design, and a cylindrical bur is needed to create small strokes. Before starting work, all tools should be laid out on the workbench in the exact order in which they will be used.

The hand holding the engraver's working attachment should slide freely over the surface being processed; for this, it is recommended to wear a fabric glove. Such a glove will also allow you not to leave hand marks on the grease-free surface of the workpiece. If you do not yet have experience in engraving, it is better to carry out the work at minimum speed. This will allow you to cut an even pattern consisting of strokes of the same depth, without damaging the workpiece.

All engraving methods assume that the outline of the design is first made, and only then its details are “drawn” with the appropriate tool. The made drawing should be processed with a felt roller, which will give it a more neat appearance and remove all burrs left by the tool from the treated surface.

If the design of the engraver or drill you use does not provide a system forced ventilation, then after 10–15 minutes of operation the equipment should be turned off and allowed to cool naturally.
