A screwdriver is indispensable tool both for professional builders and for any man involved in minor household repairs. The main thing is that this tool does not fail at the right moment. This article will tell you how to choose a screwdriver.

Where does the choice of a screwdriver begin?

Choose the right tool It’s not difficult, the main thing is to take into account several aspects:

Tool functionality
Specifications,
Types of screwdrivers,
Additional functions.

The screwdriver is functional tool. With it, you don’t have to waste time on manually tightening or unscrewing screws, which means it will become a good assistant in assembling/disassembling furniture, and in any installation work, and in drilling various materials.

Given these functions of screwdrivers, when purchasing, it is important to think about the maximum diameter of the screw. Standard size diameter is 5 mm, but in some models the diameter reaches 10 or 12 mm. The difference is quite significant. The same applies to the drilling diameter.

To better understand what parameters to choose a screwdriver by, you need to at least roughly know how it works.

Screwdriver device

The tool has few main components, and the screwdriver itself consists of:

A battery that consists of a whole set of batteries. All these elements are united by one body.
Gearbox. It can be the simplest - the so-called gear wheels in the amount of several pieces or planetary. Planetary, in turn, can be single-stage or two-stage. This type of gearbox has a more complex operating mechanism.
Speed control systems.
A motor providing direct current, which is represented by a cylinder with permanent magnets,
A system that limits the load.

These parts of the tool will determine its specifications, which should be given great attention when purchasing a screwdriver.

What technical characteristics of a screwdriver should you pay attention to when purchasing it?

The characteristics of a screwdriver will depend on its type. It is customary to distinguish two types: a screwdriver for professional work and for housework. They differ in function, scope and frequency of use. A professional screwdriver is more powerful and is made for heavy loads.

Note!

An amateur tool is not very functional, but its work is not as fast and not as frequent, so it is not suitable for professional builders.

Household screwdrivers are most often cordless and quite lightweight, and with homework they cope quite well.

These two types of screwdrivers have different technical characteristics, namely, they differ in power and speed. Power is measured in torque; for an amateur tool it is in the range of 10-15 Nm, and for a professional tool it is around 130 Nm. The speed is measured in revolutions, for the first it is about 500 revolutions per minute, and for the second it is about 1300 revolutions, which allows it not only to tighten bolts, but also to drill holes in different materials.

They also need different amounts of time to recharge. A professional screwdriver charges in 1 hour, and a household one in 3-6 hours. They also have different levels of regulation - from 5 to 22. Amateurs do not need many adjustments, while professional ones work at maximum capabilities.

Cordless screwdriver

Construction and installation work often take place in places remote from electrical power. This is where cordless screwdrivers come to the rescue. With it you can easily carry out high-altitude work and work on those objects where there is no electricity yet. In addition, you don’t have to carry a wire everywhere.

Another advantage of a cordless tool is its weight; it is lighter than a corded one.

When purchasing such a tool, it is worth considering that from time to time it will run out of charge and will have to be charged. Therefore, it is better to immediately buy a second battery. However, the price of the battery itself can be quite high.

The answer to the question: “Which cordless screwdriver is better” will depend on its manufacturer and on the type of battery itself. The most reliable cordless screwdrivers from the following manufacturers:

Metabo,
Makita,
Hitachi.

The battery itself in a screwdriver can be of three types:

Nickel-cadmium,
Nickel metal hydride,
Lithium-ion.

Types of screwdrivers

They differ in:

Number of charges. The first usually withstands about one thousand charges, the second - about five hundred charges, and the third battery is considered the most capacious.

Availability of memory. The first two types have a memory effect with reduced battery capacity due to incomplete charging.

Temperature resistance. Nickel-cadmium is not afraid of frost, and can be safely used outdoors in winter time of the year. But the last two types of batteries are afraid low temperatures, and are not suitable for working in the cold.

Security level. Considered the most environmentally friendly lithium ion battery.

Charger for cordless screwdriver

To charge a cordless screwdriver, you will definitely need a charger. They come in two types: standard and pulse.

The standard charger is suitable for household screwdrivers.

Note!

To fully charge the battery with such a charger it will take from three to six hours.

Pulse charging is suitable for professional screwdrivers. Such chargers have increased efficiency and charge the battery in just an hour.

Proper charging of the battery must take place at a certain temperature - from +10 to +40 degrees. Typically the battery gets very hot during charging and therefore requires cooling. A special light indicator will help you determine whether the battery is charged. The screwdriver charger circuit is not at all complicated, so if it breaks down, you can repair the charger yourself, using special literature.

Screwdriver

Corded screwdriver

Cordless screwdrivers are, of course, very convenient to use, but they are also quite expensive. Corded screwdrivers are more affordable. In addition, many will find such a tool more reliable.

In general, corded screwdrivers have quite a lot of advantages: reliability, reliability, high power, durability and the possibility of continuous operation. But with all this, they have one big drawback: connection to the power grid. Of course, this is not a disadvantage when the work is carried out indoors, close to a source of electricity, but when working at height, for example on the roof of a house, this becomes a big disadvantage.

Corded screwdrivers, unlike models with an autonomous power supply, provide, under certain conditions, greater productivity and continuity of work. Below we will consider which corded screwdriver is better when carrying out repairs and finishing works at home, furniture assembly, etc.

The most important characteristics of a screwdriver

When choosing a screwdriver, attention should be paid to the most important operational parameters of the device. Among them are:

Power. Determines the performance and weight of a power tool. Screwdrivers household use Usually 450-650 W is enough power.
Torque. Directly determines performance, characterizing the force that the tool provides when rotating the bit. The magnitude of the torque determines the material the screwdriver can work with, as well as the length and diameter of the fastener.
Reversing mechanism. Its presence allows you to remove fasteners.
Rotational speed, ways to regulate its value. Determine the possibility of using the device in different conditions.
Ergonomics– comfortable grip, low weight and other characteristics responsible for the comfortable operation of the power tool.

An ordinary electric household screwdriver with a power of up to 300 W is capable, for example, of screwing a self-tapping screw into a thin metal surface. More demanding work requires power tools with a power above 650 W. Such devices will be classified as professional, the power of which reaches 850 W.

The torque of a household tool is usually 25-30 N*m. This allows you to wooden base tighten approximately 70mm self-tapping screw. If there is a need to work with more powerful fasteners, it is advisable to use devices with a torque of at least 40 N*m.

The rotation speed of the screwdriver chuck for most models is 0-800 rpm, which is quite sufficient when working with fasteners. This characteristic is adjustable, but in different devices the speed can be changed by changing the force of pressing the button or by setting desired value regulator wheel or toggle switch. When performing a large volume of the same type of work, the second option for controlling the rotation speed is preferable.

Types of corded screwdrivers

The devices differ in the type of cartridge - the mechanism for holding the nozzle (bit):

Devices with a toothed (key) chuck in which the nozzle is secured using special key. This process requires some time and effort, but this mounting option is highly reliable.
A screwdriver with a quick-release chuck is a very convenient mechanism in terms of ease and speed of changing attachments, but it is not reliable enough when working with hard materials. There are single- and double-sleeve cartridges with one or two rotating rings.
The bit chuck is used exclusively for screwdrivers, while the types of chucks already described are also used in drills, drill-drivers, etc.

The devices also differ in the diameter of the cartridge, which determines how powerful the nozzle can be used in the work. Non-professional power tools are usually equipped with a chuck with a range of 0-20 mm.

You also need to know how to choose a network screwdriver with a drill function implemented in the device. These power tools are called drill drivers. Unlike simple models they usually have two speed adjustment ranges:

from 0 to 400 rpm – work with the fastener;
from 400 to 1300 rpm - when drilling.

The power tool in question may also differ in design by the type of motor - with or without brushes. The latter are more expensive, although they work more smoothly, with low noise and do not require special maintenance (brushes need to be changed quite often, so some manufacturers even equip their power tools with an additional set).

The best screwdriver for solving most problems is a combined one, which incorporates the advantages of not only network, but also battery-powered devices. Works as if it were mains powered, having sufficient power even when drilling hard materials, and from its own battery, without needing access to an outlet.

Choose the right screwdriver

The main thing you need to pay attention to when choosing this power tool is the power and the torque associated with it. For home and work, for example, with furniture, when you need to tighten relatively small screws or assemble some element, a screwdriver with a torque of 10 to 30 N*m will be quite sufficient.

Drilling wood can be done with a drill-driver with more wide possibilities and a moment corresponding to 30-40 N*m. If one of the purposes of the tool is drilling brick, concrete or metal surfaces, then the torque of the screwdriver must exceed 40 N*m.

Which screwdriver to purchase must be decided in accordance with one more characteristic. Manufacturers usually indicate in the equipment specifications the maximum diameter of fasteners that a given screwdriver can work with. In most devices this is 5 mm, although there are models capable of tightening 10 and even 12 mm fasteners. In devices with a drill function important parameter – largest diameter drilling. It can also be up to 13 mm in selected models.

Try to buy a tool that you can work with comfortably and safely. Many devices have auxiliary functions:

blocking the power button;
backlight working area using an LED flashlight;
reverse mode when unscrewing fasteners.

Also, ease of use is affected, for example, by the presence of an additional handle in the center, rubber cover handles that prevent the tool from slipping.

The best models of corded screwdrivers

Below we will consider which screwdriver to choose - a high-quality and inexpensive household one or a semi-professional one. Let's consider the characteristics of models, including domestic ones.

A domestic, inexpensive 260-watt hammerless drill/driver, it weighs only 1.4 kg and is easy to use. Handle with anti-slip pads, chuck type – quick-release. Torque with a maximum value of 25 N*m is adjustable. Speed mode – two-position.

Quite powerful in household use 350-watt hammerless screwdriver with drill function. The quick-release chuck has a reverse function and electronic rotation speed control. The device weighs only 1.2 kg, the body is made of plastic, reinforced with fiberglass. Maximum torque 12.3 N*m, maximum speed 4000 rpm.

Lightweight and compact, at the same time powerful household drill/driver with a maximum torque of 38 N*m and a rotation speed of 1600 rpm with electronic adjustment. The kit includes a case, a set of bits and drills. Six meter network cable allows you to work without the use of extension cords. You can decide which corded screwdriver is better in comparison with a semi-professional inexpensive model.

Very semi-professional inexpensive model domestic production. The power of the screwdriver with drill function is 500 W, the rotation speed of the keyless chuck is 2600 rpm. Sold with a set of additional brushes.

How to choose a screwdriver (video)

From the presented video you can find out how corded screwdrivers differ from each other using the example of four selected models:

Which screwdriver is best to choose depends on the tasks solved with the help of this tool. Simple jobs Installation of the fastener can be carried out using an inexpensive low-power corded screwdriver with a quick-release chuck. If, in addition to standard tasks, you periodically need to drill holes in metal, wood, and even concrete, you can choose a drill/driver with sufficient power and a reliable key chuck.

In contact with

In the process of repair and construction, the question always arises about which cordless screwdrivers are better and how to make the right purchase in a market that is so abundantly filled with various companies?

A screwdriver is one of the most popular tools.

Whether you decide to assemble plasterboard shelves, screw self-tapping screws into a wall, build a dog house, make a gazebo in the yard, or assemble furniture, you cannot do without this tool.

This is a universal tool that can replace several at once, for example, a drill, which is why it is so necessary for home purposes for anyone who decides to do repair work.

However, no matter how versatile a screwdriver is, it also has its pros and cons.

And since you are reading this article, it means that you are probably thinking about buying it.

We will tell you about all the subtleties in this article and help you choose exactly the one that will be useful to you for your home and work.

Of course, it is impossible to say that one tool is bad and another is good; each company has certain requirements and areas of application for its tool, for example, some manufacturers have a screwdriver equipped with an impact function, it also combines a drill, such the tool will do for making holes in concrete and wood.

It is up to you to choose among this rich assortment; we will only describe in detail the characteristics and selection criteria.

Cordless and cordless tools have their own advantages, and which screwdriver is better is up to you to decide. Our article will tell you what would be wiser to choose for specific purposes, talking about the main features of each of them.

Battery device

Independence is the main advantage. With independent battery backup, it does not require a constant power source.

Such a device can carry out work even where electricity has not yet been installed.

Mobility - an independent battery makes it possible to work without difficulty at high altitudes, it does not interfere with frequent changes of work place, the absence of a wire prevents snagging, and it does not cause inconvenience during use.

Limited charge capacity. Despite all the advantages, a cordless screwdriver requires an intermittent power source for charging.

Therefore, when purchasing a cordless screwdriver, it would be wise to buy two batteries for it at once - while one is charging, the second can be used.

Network device

Uninterrupted workflow - with a regular power supply present, there is no need to interrupt for charging.

Light weight - a corded tool, unlike its cordless counterpart, is lighter, which will allow it to work tirelessly for longer.

Cost - a network device is cheaper, and its price is affected only by its technical characteristics; there is also no need to spend money on additional batteries.

Professional and household - which is better?

Any tool called “professional” inspires much greater confidence in the buyer.

Screwdrivers equipped with a shock wave were no exception, combining a drill and becoming a universal tool.

When you buy such a model, you are sure that the service life will be long and the functionality will be extensive.

But the price of a professional tool is many times higher and often becomes a reason in favor of choosing a household one.

There is also an external difference between screwdrivers, as can be seen in the photo below; a professional tool combines a more ergonomic design.

If you're only going to use it at home, then there's no reason to buy a professional one. The only difference is the torque - for professional ones it is 130 Nm, for household ones - 15 Nm.

So, for tightening or unscrewing screws and self-tapping screws, 10 Nm is enough. Therefore, in some cases it will be wise to opt for a screwdriver for the home in order to save Money.

A professional screwdriver has one important difference - the battery is fully charged in no more than an hour.

So, when making your choice, consider what is more important to you - saving time or money. For most buyers, waiting 3-5 hours to charge a household screwdriver is not that important.

Main characteristics of household and professional screwdrivers

Household screwdriver:

low cost;
low productivity;
low power;
simple assembly;
cheap spare parts;
small battery capacity.

Professional tool:

high quality assemblies;
powerful motor that can withstand heavy loads;
long and fast battery charge;
convenient design, fits easily in the hand;
high price corresponding to the quality;
reliability;
shock-resistant housing.

To choose such a device, you need to approach the matter seriously and responsibly; this is a very complex mechanism.

And the main determining factors when choosing are:

Firm;
Price;
Convenience.

Let's go over these points in more detail.

Firm

Construction stores mainly offer products from companies such as:

Bosch (Bosch, Germany);
Makita (Makita, Japan);
AEG (AEG, Germany);
Hitachi (Hitachi, Japan);
Hilti (Hilti, Liechtenstein);
DeWalt (Dewalt, Germany);
Black&Decker (Black & Decker, USA);
Metabo (Metabo, Germany);
Interskol (Russia);
Zubr (Russia);
Sparky (Sparky, Germany);
Skil (Skil, Netherlands).

Of course, it's incredible to choose among large quantity difficult. Most of the instruments presented are made in China, which is not always a bad thing.

The debate over which company is better, Bosch, Makita, Hitachi, Interskol or AEG, does not subside. We will have to figure out the choice later.

Price

The cost primarily depends on the promotion and rating of the company, so the Hilti brand is not popular with us due to the inflated price category and low characteristics.

Although the service is excellent: free service by the service center for two years from the date of purchase, a company employee will come to a place convenient for you, pick up the tool, repair it free of charge and bring it back.

The company provides a lifetime warranty. After two years of use of the device, a repair fee of no more than 33% of its cost will be charged.

But, unfortunately, according to reviews, the tools of this company break down very often.

Such a device is useful only at a construction site, where the tool is provided by the foreman, where it will often be dropped, in which case the warranty will play a positive role.

But still, for this price you can buy 2-4 Bosch screwdrivers with similar characteristics. In terms of price, a screwdriver from Interskol is ideal for your home.

This is an inexpensive and very high-quality equipment, although it is not ergonomic, it looks rather rough.

Convenience, size

This point is completely irrelevant for use at home. But it is essential for craftsmen who use a screwdriver for hours.

In this case, size is of great importance. A small tool is more comfortable to hold, the hand does not get so tired, it can be used to get into the most inaccessible places, but it is also more difficult for them to screw in a screw.

Now about convenience. Before purchasing a device, you need to pay attention to the angle of the handle in relation to the barrel.

If it is too sharp, as shown in the photo below, then with regular use, the result will be a permanent callus between the thumb and forefinger.

Screwdriver battery - types, characteristics

This is the most important point when choosing.

IN modern devices Three types of batteries are used:

nickel-cadmium;
nickel metal hydride;
lithium-ion.

Advantages of nickel-cadmium batteries:

This type of battery can remain in a completely discharged state;
Low cost;
Not afraid of low temperatures;
Recoverability after long periods of lying down.

Flaws:

Relatively short time for remote work;
The battery can only be charged after it has been completely discharged. Otherwise, the duration of its charge is reduced;
Fast discharge, after fully charging in an inactive position for a week, it will completely discharge.

Pros of nickel-metal hydride batteries:

Environmentally friendly;
Small size;
Can be charged at a large percentage discharge, the charge duration does not decrease much.

Less operating time than nickel-cadmium batteries;
The price category is higher in contrast to nickel-cadmium batteries;
Discharges by 10% during the first day;
Storage in a discharged form is prohibited;
Fear of sub-zero temperatures.

Nickel-metal hydride batteries are now practically not widespread.

Pros of lithium-ion batteries:

You can charge it at any percentage of discharge;
Self-discharge no more than 20% per year with proper storage;
Fast charging time (from half an hour);
Long service life, 5 times longer than nickel-cadmium batteries.

High cost of charging and battery;
It is impossible to start charging with a completely discharged battery;
Does not tolerate sub-zero temperatures.

Top most popular screwdrivers

Makita. You need to choose it if you want to purchase an inexpensive but high-quality device, pay attention to this company. Despite not the most high rating- this is deservedly one of the most suitable options. This device is suitable for both home and professional use;
Interskol. If you need to choose a reliable screwdriver for your home that will serve you for a long time in any conditions and does not require expensive investments, then this is the best option;
Bosch. Characteristic difference– high reliability, power, great capabilities, fast charging and convenience. It is intended for professional use and home purposes, high price for excellent quality. Combining the impact function, it is able to replace a drill.

Follow all these rules, and you can buy a screwdriver that will make you happy while working.

It's good to have everything on hand necessary tool, including a screwdriver, drill and hammer drill. But buying three devices at once can cost a pretty penny. As a good alternative to these three tools, many manufacturers offer corded screwdrivers.

This technique works well for drilling, screwing and grinding. Naturally, here we're talking about only about the best corded screwdrivers that have high-quality components and meet professional requirements. Therefore, it’s not worth taking any model, and we’re not just talking about the cost of the device.

We will try to understand this issue and determine which corded screwdriver is better than another and why, and also identify the most promising manufacturers of this type of equipment in terms of choice. The article contains the opinions of experts in this field and reviews of ordinary owners of screwdrivers.

Difficulty of choice

The power tool market is simply bursting with an abundance of models in different price categories, as well as manufacturers. Sometimes it is difficult for an experienced consumer to choose the best option, not to mention inexperienced users. Even reviews of networked screwdrivers do not always help, because on large Internet sites they are mostly just purchased. Therefore, it is better to collect information about the device you like on specialized forums and resources, and not on the shelves of online stores.

All corded drills and screwdrivers have a similar design: motor, body, chuck, trigger, lock with reverse and speed controller. And some critical difference is determined as you use the device. Not all companies that produce this type of equipment are good on every point, so you need to approach the choice carefully and theoretically correctly.

Manufacturers

All manufacturers can be divided into “ours” and “others”. Domestic equipment attracts primarily due to its democratic pricing policy and abundance of inexpensive spare parts. Yes, and figuring it out yourself won’t be difficult.

Imported models are quality, reliability and a long history with authority. Of course, here we are talking about venerable brands, and not about those who are just taking their first steps. Unlike domestic devices, foreign networked screwdrivers cannot be called ascetic or inconvenient. Foreign manufacturers spend enormous amounts of money on the study and development of not only technical innovations, but also on the ergonomic component.

Foreign manufacturers

Among the import suppliers the following brands can be noted:

Makita.
Bosch.
Hitachi.
Metabo.

Reviews about these manufacturers are entirely positive. Their equipment is reliable, efficient in operation, and of high quality in many respects. If there is any negativity in the responses, then this mostly applies to local service centers and delivery. As a rule, there are no complaints about the work of networked screwdrivers themselves.

Domestic manufacturers

The following companies are enviably popular among domestic suppliers:

"Interskol".
"Bison".
"Energomash"

Reviews of these manufacturers are mostly positive, however, the series must be selected with due care so as not to run into defects or any critical design flaws.

Next, we will consider several of the most successful network screwdrivers from the above brands from different price categories. All models can be purchased both in branded offline and online stores, so there should be no problems with “touching” them.

"Interskol DSh-10/260E2"

The Interskol non-impact corded screwdriver with a power of 260 W is enviably popular among domestic consumers. The model received a gearbox for two gears - 450 and 1800 rpm. The first speed is perfect for tightening screws, and the second is perfect for drilling wood and steel.
