How to make a polishing machine from an angle grinder. Homemade grinder from a grinder

Even if you purchase and install the necessary additional accessories on the angle grinder, this still does not mean anything. Treatment different materials requires certain knowledge. Without this, it will be difficult to achieve the desired quality.

Such a question may be confusing, because this is what an angle grinder is - a corner angle Grinder. But it is very universal and must be prepared for each operation. To prepare the grinder for grinding, you need to purchase a support wheel that is installed directly on the machine shaft.

To process wood, you need to stick an emery pad on this circle. The number of sandpaper is selected for the immediate moment of work. On sale you can find both a grinding wheel of the required diameter and sanding wheels of the appropriate size. Sanding wheels with Velcro are also available for sale, which are very easy and quick to change on the tool.

To convert our grinder for grinding concrete, it will be good decision purchase a special protective cover-anther. It is good because it has a connection for connecting a vacuum cleaner. Well-known housings are produced by Hilti. The casing from this company has a sliding sector that opens part of the wheel for grinding in the corners.

Grinding metals with a grinder is usually performed with standard metal grinding wheels. They have different diameters, different thicknesses and different grains of the grinding surface. But, if you are going to sand an indecently rusted surface, then first you need to go over it with a metal brush. Such brushes required diameters also on sale.

How to grind with a grinder

We must not forget that sanding always involves a lot of dust. When preparing for sanding, don't forget about yourself! A protective mask and respirator are the best assistants when grinding. You can also find an option where the mask is combined with a good respirator.

The respirator filter will clog very quickly, so you need to prepare several pieces at once for prompt replacement. Only after thorough preparatory work can you begin sanding.

Sanding wood + (Video)

Wood is a unique material. It can be sanded quite well by hand, but with a grinder you can achieve very good results. Some snobs claim that you can’t grind with a grinder at all, but this is due to ignorance and inability.

The main secret is that the grinder is used at minimum speed. If the grinder has a speed switch, then there will be no problems. At high speeds, the sandpaper will become clogged with wood very quickly and very tightly. In this mode, it will not be enough for even five minutes of work. The optimal speed is no more than 6000 rpm.

Another secret is not to sand the entire area of ​​the wheel. If you sand the entire surface, circular marks will remain on the wood. To ensure that there are no sandpaper marks left at all or that they are minimal, you need to sand only with the upper sector of the wheel. The movements of the machine should be along the grain of the wood.

Using this method you can get excellent results when sanding lining. The board becomes smooth and does not retain tool marks. Just don’t get carried away and change the sanding pads on the wheel in time.

The frame is polished in a similar way. Here it is desirable that the support plate is thin around the edge. With such a plate it will be easier to sand narrow junctions of logs. Otherwise, this work will have to be completed with a chisel.

We work on concrete + (Video)

If you were unable to purchase a branded protective boot with a nozzle for a vacuum cleaner, then you can make it yourself. To do this, take a used putty or glue bucket with a diameter slightly larger than the circle of the grinder. We cut off the bottom part at a height slightly higher than the assembled sanding part.

We cut a hole in the bottom for installation on the gearbox and a hole for the plastic plumbing corner outlet. Now we connect the vacuum cleaner hose to the nozzle and work quietly.

The grinding wheel must be designed for stone processing. It is preferable to grind concrete and concrete surfaces using the entire surface of the wheel. This will save processing time and level the surface well.

When grinding a concrete floor, you must constantly control the plane using a construction ruler, because due to the different densities of concrete, indentations can be made. To process the joints between concrete pours, it will be sufficient to achieve one level combination.

It is good to grind concrete floors and surfaces with a Matrix diamond grinding cup. If the grinder is 150 mm, then the cup is 125 mm.

Grinding metal surfaces + (Video)

The metal is polished according to different requirements. Most often, the metal is ground for painting or for further polishing. The main tool is a support cup with replaceable sanding pads. The selection of sandpaper depends on the degree of processing and the condition of the metal.

When sanding, you only need to work with part of the disc. There should be no untreated areas left on the surface.

It is advisable to coat the treated surfaces of ordinary steel with a primer. Moisture in the air can very quickly coat the metal and cause rust.

A grinding or polishing machine is required for painting work. There are many models of such devices available in tool stores and other retail outlets. However, in some cases it is advisable to create a polishing machine yourself. This article discusses various options such homemade devices and the process of their creation is described.

The simplest polishing machine

The easiest way to make your own is a polishing machine designed to work with grinding discs. To create this device you will need the following main parts:

• electric motor;
• power unit;
• battery.

The electric motor can be removed from various electric tools and instruments. For example, components of a computer power supply or disk drive are suitable.

You can also use an electric motor from a fan, and a household battery is suitable to drive the electric motor.

In addition to the above components, you will need a board, it needs to be sanded sandpaper. Next, the battery and electric motor are secured to the board with screws and connected with wires. It is also necessary to install a switch in this electrical circuit, securing it to the board. The wires should be secured with a stapler to prevent loosening.

The working element of the structure under consideration is represented by a circle. You can use branded products or you can make grinding disc from sandpaper with your own hands. To do this, you need to cut two sectors from a fragment of the source material and fasten them together with their back sides, gluing them together.

To ensure the drive of the abrasive disk from the axis of the electric motor, two bushings will be required. The diameter of these devices is determined based on the corresponding parameter of the motor axis. It should be taken into account that different electric motors have axes different diameters. The considered grinding machine can be used for processing both wooden and metal surfaces, including during body work.

Motor and polishing discs

Remember that the functional parameters of such a homemade grinding machine are determined by the individual parts from which it is assembled. In this regard, you should use an electric motor from a fan, since the motor from a computer has less power, which may not be enough for some types of work. In addition, sanding discs made of sandpaper are not optimal devices of this type. Instead, you can purchase branded circles without large diameter, for example, for a drill.

You can create a more powerful stationary version of the grinding machine with your own hands. For it you can use a motor from washing machine and equipped with large diameter grinding wheels. In addition to polishing discs, such a device can be equipped with sharpening and abrasive discs.

Belt sander

The working element of machines of this type is an abrasive sanding belt. Operating principle tape devices consists of rotating an abrasive belt connected in a ring, driven by an engine through a transmission and drums. One of the drums is the leading one, and the other is the driven one. The first of them is driven by an electric motor through a transmission, usually represented by a belt drive.

Some belt sanders are equipped with a device that allows you to change the speed of rotation of the drive drum, which provides different operating modes. The tape can be located on the frame vertically, obliquely or horizontally, depending on the purpose of the device. To adjust the degree of tension, a tension roller is used. Since grinding work is characterized by the release of large amounts of dust, it is advisable that the grinding machine be equipped with an exhaust device.

It must be taken into account that many design features grinding machine, such as, for example, the diameter of the drums, rotation speed, grain size, the dimensions of the abrasive belt, the design of the work table, which determine the main functional parameters of the device in question, are selected depending on its purpose. The following types of working surfaces are classified for the processing of which grinding machines are oriented: curved, flat, edges and ends, intermediate layers of paint and varnish coating.

What is a grinder made of?

You can create your own belt sanding machine based on an industrial design, which involves moving the belt over flat surface working table with the abrasive part facing outwards. Wherein homemade device will differ from the branded counterpart large sizes and permanent installation. For these works you will need an electric motor, for example, from a washing machine, wooden or metal panel, chipboard, material for abrasive tape, glue.

Since the transmission in the form of a gearbox or belt drive significantly complicates the design of the tool in question, homemade models try not to use it. To do this, you can equip the device with an electric motor with a power of 2-3 kW with a rotor speed of 1500 rpm.

In this case, with a drive shaft radius of 10 cm, the belt will move at a speed of about 15 m/s. It should be taken into account that the design in question does not provide for adjustment of the belt rotation speed. However, it is possible to regulate the degree of tension due to the fact that the tension shaft, rotating on bearings to reduce friction, is mounted on a fixed axis, which can be shifted relative to the work table. The drive shaft is fixed to the electric motor shaft.

You can make a work table for such a grinding machine yourself from wooden beam or sheet metal. It should be borne in mind that metal options allow you to process more complex objects. The dimensions of the working table of the tool in question are determined based on the dimensions of the belt and the distance between the axes of the shafts, as well as its purpose. Bevels should be made near the shafts in the work table in order to ensure smooth contact of the tape with it.

Drums can also be made by yourself. Chipboard can be used as the starting material for these elements. Squares with side lengths of 20 cm are cut out of the slab in such quantities that their total thickness when superimposed on each other is about 25 cm. Then these blanks must be turned into disks with a diameter of 20 cm by processing lathe. You can process the cut fragments separately, but it is more convenient to grind them all at once, placing them on the axle and clamping them. It should be taken into account that the drums must have edges of a larger diameter in comparison with the central part to automatically hold the tape.

Where can I get the tape?

The sanding belt can be made by hand using paper or fabric. The second option is considered more preferable. The fabric can be represented by calico or twill. It should also be taken into account that the rare filling of the belt with abrasive grains, amounting to less than 70%, allows you to reduce the degree of its filling with dust during operation.

The main characteristic of an abrasive belt is the grain size. This parameter is determined based on the number of the sieve through which they can leak. Based on grain size, abrasive belts are divided into coarse-grained (12-80), medium-grained (80-160), and fine-grained (160-4000).

Abrasive grains can be presented artificial materials or minerals with high hardness, such as, for example, silicon carbide, corundum. They are fixed to the base by gluing or electrically. In the first case, the grains are evenly poured onto the surface of the base, previously coated with an adhesive in the form of synthetic resins or hide glue. Electric field used to orient abrasive grains with sharp edges upward, which increases the functionality of the belt.

You can make a belt for a sanding machine with your own hands from sandpaper in the form of rolls, which are cut into fragments of the required size.

It should be taken into account that the length of the tape is determined by the method of fastening the ends of the cut fragment. It is possible to connect them at an angle, butt and overlap. In the first case, the ends are cut at an angle of 45° and a fabric overlay is glued under the joint. Overlapping joint requires pre-cleaning hot water a fragment of one of the ends 8-10 cm from the abrasive grains. Then the cleaned area is covered with glue and the back side of the other end of the tape is placed on it and the junction is compressed. Optimal thickness abrasive belt is 200 mm. A roll of source material 1 m long is enough for 5 tapes.

You need to cut the frame yourself from a thick sheet of metal. At least one of its sides must be cut straight to accommodate the mounting of the motor platform by screwing three bolts through pre-drilled holes in the frame.

Minor scratches or chips on the car body do not need to be fixed in specialized workshops, nor do you need to buy paints and putties in stores. It will do a great job with minor damage and unevenness. This action will correct the shortcomings and save a significant part of the budget. All motorists have a lot of questions about polishing technologies, related products for polishing work, cost, grinding machines and many others. The main one is the possibility of correct and high-quality polishing of a car at home.

Is the game worth the candle?

Environment, trips out of town and not always quality road surface lead to cracks, chips and scratches on the body and bumpers. Exposure to direct sunlight will cause paint to fade, resulting in the need to refinish or repair your vehicle's paintwork.

There are a lot of opinions on polishing and minor repairs, and some believe that polishing a car with an angle grinder can lead to even worse results. This opinion can be called erroneous because the correct and accurate approach to work and choice the required technology will allow you to get excellent results.

When choosing the right materials You can restore even the most neglected car to its original state. Initially, you need to determine the scope of work and select the appropriate paste and polish, among which there are several types:

• abrasive and non-abrasive - this applies to paste and polish;
• silicone polishes;
• restorative polishes.

Pastes are marked; for abrasive pastes the designations J3, J6, J7, J10 and M3 are used. Polish pastes are in demand. It's worth remembering that aerosol can Polishing is designed to give a final look and shine.

When preparing the body, fine sandpaper P 2000 is used. It clogs quickly, so it is necessary to frequently wet the surface with water. This fine sandpaper will get rid of deep scratches and paint chips.

Abrasive polishes are used to remove scuffs and scratches from car paintwork. Treatment with this product removes a slight layer of varnish, after which it will need to be restored. At the next stage of work, protective silicone polish is applied. It fills the smallest cracks, micro-scratches and adds shine.

In order not to perform the entire range of work manually, the car is processed with a grinder. When working, special circles are used. For grinding machines, eccentric ones with high runout speeds are chosen. It is better to purchase a professional tool, for example, from brands such as Makita or Bosch.

For the average motorist

For minor damage, an ordinary grinder or hand drill. The processing circles are made of wool or foam rubber. The tool must have a speed regulator to avoid unnecessary scratches and abrasions. Required type The paste is applied to the circle and a little to the work area.

Polishing should be done crosswise, gradually moving vertically and horizontally. This will allow you to apply the paste evenly and properly treat the surface, the main thing is that the paste does not dry out while working. Polishing is carried out until the desired shine appears. All excess paste is wiped off with a soft cloth or napkin.

After the area is polished, silicone paste is applied and the same actions are carried out with a softer circle. The whole job takes several hours. The final step is to apply a protective layer using a soft cloth or a special mitten. The layer should be distributed evenly so that there is no excess polishing left; all drips should be removed with a napkin.

Advantages of the method

Such a low-cost and accessible method for every car enthusiast will allow not only corrections for minor damage, but also giving the car a well-groomed appearance. The technology is simple, and it won’t be difficult to do all the work yourself. In this way, headlights, bumpers and windows can be perfected.

When processing headlights, do not use silicone polishes. In some cases, it may be necessary to treat the headlight glasses with sandpaper R 600-800, it all depends on their original condition.

About prices

If you count approximate cost of the entire amount of work, then car centers for polishing will announce a price of 150 USD. The price includes polishing with all the products offered by the center. Be sure in excellent result, giving the car into the wrong hands is not always possible. Moreover, many of these services do not bear responsibility.

The work done yourself will cost much less. On average, a can of polishing paste in an authorized store will cost more than 15 USD. One can is enough for five cars. will cost 5 USD If you don’t have a grinder or polishing machine, you can borrow it from friends or rent it; in extreme cases, a drill with the ability to adjust the speed will do. As a result, the total amount will be no more than 30 USD. In addition to significant savings, there will be confidence in quality work made with your own hands.

Why polish?

Polishing may be necessary not only for minor damage or scratches. With the help of abrasive pastes and cleaning agents it is possible to maintain it in almost its original form. Polishing the instrument panel, headlights and bumpers will keep it in perfect condition. The main thing is to choose the right type of product for a specific job.

Abrasives gradually remove top coats of varnish and paint; constant polishing will have the opposite effect.
If there is no need to process the car body, there is no need to abuse abrasive polishing. This can result in complete removal of the paintwork, right down to the metal, which will require more expensive paint restoration, varnish application and final polishing.

You can make a very convenient manual belt sander from an angle grinder with your own hands. With the help of such a tool it is good to sharpen an ax, knives, etc. Treat the surface at any angle, giving it a flat plane. In general, anyone who works with iron or wood will appreciate this mini machine.
Sharpening the cutting edge of the ax:

With this sharpening, the corner will not float away.

How to make a belt sander from an angle grinder

The mount for the angle grinder will be made from a piece of thick steel, about 10 mm thick. We drill a hole for the neck of the angle grinder.

We cut a wide slot.

Using a grinder we cut off the fastening.

Next, we clean and polish so that everything looks beautiful and safe.

With paws clamping device drill a hole.

Then cut a thread on the wide side.

As a result, this mount can easily be put on the angle grinder and clamped so that everything is held tightly.

Let's try it on.

Now you need to make a roller that will rotate the sandpaper tape. We take chipboard and use large diameter bits to cut out round pieces. To obtain a wide roller, we glue the round pieces together.
Then use a feather drill to drill a hole in all of them at once.

Then we clamp it in a vice and use a triangular file to make an internal hole for the hexagon.

Like this.

We take a wide nut and make notches on the planes with a file.

They are needed to help the nut stay in the wood better.

We dilute two-component epoxy glue and glue the notched nut into the wooden roller.

After the glue has dried, we clamp the roller into the lathe.

We sew under the ellipse. This is necessary so that the tape does not fly off. Then sand it with sandpaper until smooth.

It came to the second video. It is made of three bearings pressed onto the main line.

Let's make two such ears.

We put it on the edges of the protruding shaft.

Let's weld the plate. The result was a U-shaped part holding the roller.

To prevent the shaft from flying out, we fix it by welding

Now let's make the frame. It will take two steel pipes of different diameters so that one fits into the other.
A flat overlay is welded onto a larger diameter pipe. It is needed in order to press on the tape while sanding.

We weld a roller of bearings to a thin pipe.

Take a ring made of sandpaper (sold in hardware stores), insert the pipe into the pipe and estimate approximate size of the entire device.

We saw off the long ends of the pipes. We make a wide groove in a thin pipe, and a hole in a thick pipe.

We weld a nut to the hole.

To the ring fastening - a section from the pipe.

How to make a sander

When working with wooden surface is coming to an end, the final polishing stage begins. To perform grinding without burrs, scratches, and to beautifully round sharp corners of any part, you need to use a wood sander. This tool will help perform professional grinding even for a beginner who has picked up the device for the first time. If you wish, you can make a grinding machine yourself, using only available tools.

The industry produces several types of machines, differing both in design and purpose. Here are the main ones:

• Eccentric or orbital, in this case the base of the tool simultaneously rotates around its axis and along a certain orbit. It turns out that each time it passes in a slightly different place, so scratches and burrs are rubbed out more and more with each pass.

• Vibration model. Here the working sole carries out reciprocating movements with a frequency of about 20,000 movements per minute. It is through these movements that grinding occurs.
• An angle grinder, which is popularly called a “grinder”. This tool is used for rough processing of parts, large logs, etc. For processing they are used abrasive wheels required grain size.
• A belt sander typically used for large surface jobs. Structurally, it consists of rollers driven by an electric motor, on which sanding tape is worn.

Making a belt sander with your own hands + ()

Making a belt sander yourself is not at all difficult; you need to complete the following steps:

• pick up suitable materials and details;
• create a reliable basis for securing the tool;
• install a suitable countertop;
• secure vertical racks with tensioner and drum;
• mount the motor and drums;
• secure with sanding tape.

To process fairly large parts and elements, it is necessary to make a large copy of a serial grinder. For example, if you take an electric motor with a power of 2 kW or more powerful with a rotor speed of 1500 rpm, then you don’t need to install a gearbox. The power of such an engine is quite enough to rotate a drum about 20 cm in diameter and process parts of about 2 m.

You can also use Electrical engine from old washing machine. In this case, the frame is made from a thick sheet of iron, preparing a place for installing the motor and carefully securing it with bolts to eliminate vibration. The design of such a machine consists of 2 drums, one of which is fixed, and the second can be tensioned and rotates on bearings around an axis. It is advisable to make the base for the machine from metal or several sheets of thick plywood. The drums are made on a lathe from chipboard. The tape is cut from sandpaper sheets about 20 cm wide and secured to the frame. The larger the table size, the larger the parts can be stacked and processed in the future. Blueprints finished products can be found on the web.

Making a grinder from a grinder

Many may say that the “grinder” is the same as an angle grinder, but there are some subtleties hidden here. It should be borne in mind that the angle grinder has very high speeds and often quite a decent weight. To polish a surface with a grinder, you need to have considerable experience in this matter and use special polishing discs and circles. The grinder has much lower engine speed and weight. No factory sander required to operate certain experience and dexterity.

You can independently make a good grinder from an angle grinder, which is not inferior in its parameters to a factory machine, only by modifying it electrical diagram, by installing the regulator at lower speeds and by using special grinding attachments.

Making a grinder from a drill

To transform ordinary, household electric drill The grinding machine must be equipped with a special attachment - a working drum or a special support plate, depending on the task at hand.

The support or sanding pad is a plastic or rubber base with sandpaper glued on and a shank for clamping into the drill chuck. Discs with a flexible shaft are suitable for working with a loose drill, while those with a rigid shaft are best used only for a well-fixed drill.

Sanding drums for a household drill are structurally a regular cylinder, a shank and sandpaper glued to the cylinder. When using drums working surface The grinder is located parallel to the axis of rotation.

Making an orbital sander

Currently, you can only make an orbital machine with your own hands from a broken orbital machine. This is due to a complex device for rotating the working disk, which is quite problematic to replicate on your own. You should also keep in mind that a machine manufactured by a specialized company will not cost too much, but making it yourself will be very difficult and will take a lot of time.

Making a grinder from a computer hard drive + ()

Any old hard drive can be converted into a miniature grinding machine. To do this you need to follow these steps:

• completely disassemble the hard drive and remove from the case everything that is located to the left of the magnetic disks;
• cut out a working circle from sandpaper, make a hole in the center of the circle for the spindle;
• stick several strips of double-sided tape onto the rotating disk of the hard drive and secure it with sandpaper;
• make a protective screen to protect the eyes from the possible ejection of the manufactured sanding disc;
• to plug finished design to the power supply from the computer and use it.

Of course, this design does not have high power, but it is quite possible to sharpen a small knife or scissors.

Functions of a grinding machine.

The good thing about the drill is that I changed the attachment and got new tool. Now we will talk about using your impact drill as a powerful tool for processing various surfaces.

Rough surface treatment.
To clean wooden and metal surfaces from paint, varnish, and rust, use a special drill attachment called a cup-shaped twisted cord brush. It looks like this:

When using a cord brush, follow these guidelines:
— Clamp the cord brush securely in the chuck.
- Work with the entire plane.
— Do not press the cord brush too hard against the surface.
— Do not exceed the speed indicated on the cord brush.
- Hold the drill securely and firmly in your hands.

Softer surface treatment.
The same treatment, but softer, is used with a different cord brush. This is what it looks like installed in your drill:

Sanding surfaces with sandpaper.
If you need to grind any surface or part, for example, remove splinters from wooden block, then, cutting out a circle of sandpaper, and placing it on special device(sanding disc), you will do it with ease. This is what the device looks like installed in a drill:

However, the matter does not end there. If you don’t have time, or you don’t want to cut out the circles from sandpaper yourself and then put them on the device, you can buy self-adhesive sanding discs for the drill. However, in this case you need to purchase another device called a “grinding support plate”. You take a plate, velcro a sanding disc to it and install it in the drill. That's it, you can start sanding:

The master's imagination is very rich. Below is an attachment called a “radial petal disk”. Each petal of such a disk is made of sandpaper. Also suitable for grinding after installation in a drill:

Polishing surfaces with a sponge.
A polishing sponge is also used in conjunction with the support plate discussed above. The polishing sponge is secured to the support plate using Velcro. You install this attachment into a drill. That's it, the polishing tool is ready. You take the polishing paste, apply it to the surface to be polished, then turn on the drill and start rubbing in the polish using a sponge attached to the drill:

Knife sharpening.
In stores you can also find radial grindstone for a drill, which can be used, for example, for sharpening knives. This is what the whetstone looks like installed in a drill:

Screwdriver functions.

Classic screwdriver.
A drill with a soft start can be successfully used as a screwdriver at low speeds. For these purposes, a special “bit holder” attachment is used on the drill. The holder is installed in the drill, and then the corresponding bit for the screw is installed in it. In this way you can successfully quickly tighten a large number of self-tapping screws, which is of course important during repairs. If your drill has a reverse function, then you can unscrew these screws. If your drill has an impact impulse torque, then it can unscrew even completely ancient screws that have been stuck in the wall for a long time, which have a slot for a screwdriver ground off. Therefore, I highly recommend looking for a drill with this additional feature.

Screwdriver for hard-to-reach places.
There are times when it is quite difficult to tighten or unscrew a screw (masters say “you can’t get close” to the screw).

Grinding accessories

True, this is more common in a car, but you can also encounter this during ordinary home renovations. So, to tighten and unscrew screws in hard-to-reach places, a special drill attachment is used, which is called a “flexible shaft extension.” One end of the flexible shaft is fixed in the drill, and the other is a magnetic bit holder. You install the desired bit into the holder, and now, your tool for tightening screws in hard-to-reach places is ready:

Mixer functions.

When you really get into it renovation work, then you will be faced with the fact that you will constantly need to mix something: wallpaper glue, cement-sand mixture (CSM), floor leveler, glue for gluing tiles, plaster, putty, etc. I’ll tell you right away that you can’t do this with your hands. Firstly, you will quickly get tired, and secondly, you will never be able to mix cement mortars with your hands to the state of thick, smooth sour cream! Therefore, a drill and a mixer come to the rescue. The mixer looks like this: Installed in a drill, the mixer looks like this:

How to use an impact drill

Before you start working with an impact drill, you need to set up the tool and prepare everything you need for work. Now I will talk about my drill, but for other drills the principle will be similar.

Setting the operating mode.
First, understand what type of work you have to do. An impact drill has only 2 main modes - drilling mode and chiselling mode. In accordance with this, you need to set either a “drill” or a “hammer”. Let me immediately note that you set the hammer only for operating the drill in hammer drill mode. In other cases: drilling, grinding, tightening screws, mixing cement mortars is done when the switch is set to the “Drill” position.

Speed ​​setting.
For different types work you will set different speeds. For example, if you need to drill holes in metal plate, which you want to use under the bracket, it is better to turn on 2nd speed. If you are going to make a batch cement mortar or you want to tighten screws, you need to set the 1st speed. If you are going to work with a cord brush, then usually when purchasing attachments, the recommended operating speed is indicated on the packaging. Thus, you can navigate in choosing the speed. If you suddenly don’t know what speed to set for a certain type of work, consult with professionals.

Reverse setting.
For all types of work, except for unscrewing screws, the direction of rotation of the drill chuck should be clockwise. To do this, the reverse switch must be set to the position where the arrow points to the cartridge.

Installation of the nozzle.
Depending on the nature of the work, you install the desired attachment on the drill. I have been telling you about attachments throughout this book. So, just look at the desired section.

While working.
The drill is started by smoothly pressing the start switch. (See Impact Drill Design section.) Moreover, the harder you press, the faster your drill accelerates. With the strongest pressure maximum speed will be the one you set when selecting the mode: “1st speed” or “2nd speed”. Thus, by switching the starting switch and switching speeds, you achieve a very wide speed range. If you have been drilling a surface for a long time and are tired of pressing the start switch, then for these purposes press the “Lock button” by releasing the start switch. In this option, the drill will continue to work. This is convenient because... saves your energy. You can disable this mode by pressing the start switch again.

Finally, if you are unscrewing a screw, then set the reverse switch to the position where the arrow points towards your hand. When the drill is turned on smoothly, the chuck should rotate counterclockwise.

Dangerous experiments

An impact drill will be your indispensable friend and assistant in many jobs. But there are still things that are unacceptable in operation, and I will now briefly talk about them. We will talk about a circular saw blade, which, for some reason, some people also want to install on a drill, thus building an electric saw:

Remember the rule: saw blade Do not put it on a drill. Firstly, because there is no protective casing. Secondly, there will not be the necessary pressure on the material being processed. Thirdly, the drill will “walk” in your hands, and if the saw lies unevenly on the surface being sawed off, then either the disk will fly apart, or the drill will be torn out of your hands, and no one knows where it will fly! Injury guaranteed! This is very dangerous and let's not experiment like that!

Finally

Once you gain enough experience with a hammer drill, you'll likely want more. The first thing you will encounter is that you will need to not just make a hole in the wall for a dowel, but, for example, completely drill out a thick wall with a drill with a diameter of 10 or 13 for laying wires. This kind of work will be difficult to do with an impact drill. Do not mock it, otherwise it will quickly fail. In these cases, of course, use a hammer drill.

The second point is the speed of work during repairs. If, for example, you are expecting a global installation of gypsum board on all the walls in the apartment, then, of course, in addition to an impact drill, it would be a good idea to separately purchase a screwdriver. The fact is that you will constantly be hammering the wall and turning screws. Moreover, you will alternate these two types of work so often for a long time that for a moment it will seem to you that all you are doing is changing a drill for a screwdriver. Therefore, having a separately charged impact drill and screwdriver on hand will increase the efficiency of installing drywall by several times. There is one more secret: a screwdriver weighs lighter than an impact drill and is certainly more convenient for screwing.

However, if you are new to repair, I don’t want to burden you with expensive purchases right away and I’m telling you purely my experience, which started with an impact drill and I think that this sequence of mastering the tool is the most correct. You may ask, maybe you should buy a hammer drill instead of an impact drill. I answer. A hammer drill is even heavier than an impact drill and it will not be at all convenient to use it as a screwdriver or surface grinder. Take it as a rule: a hammer drill is needed mainly for chiseling walls.
