A screwdriver, in its essence, is a substitute for a conventional screwdriver, with the only difference being that it works without the use of human force to rotate. With its help, they perform the same functionality, only its work in the process of unscrewing / tightening bolts and screws is much more efficient, and it happens faster. This tool will be indispensable when you need to screw in / unscrew dozens or even hundreds of bolts. However, the scope of the screwdriver is not limited to one screwing in of bolts. By inserting a special drill into it, they can drill holes in wooden surfaces, plastic and even in thin metal. Professional devices of this type of tools will master brick and concrete. Recently, screwdrivers powered by mobile batteries have become most widespread, and they have almost replaced mains-operated devices.

Unlike network devices, they are more manoeuvrable in operation and convenient for transportation. All this is due to the fact that they are not “tied” with a cord to an electrical outlet.
Their other advantages include:
An ordinary user hardly needs to know all the technological principles of the operation of this tool, one has only to be aware of its main parameters.
Batteries for them are:
This parameter indicates how much force the tool will use to drive the bolt, or how much force is required when drilling to overcome the load. This indicator is measured in Newton Meters (Nm). Knowing the moment of force, you can calculate the length and diameter of the bolt that the screwdriver can screw in. The higher this parameter, the longer and thicker the bolt can be.For example, a professional tool with an indicator of 40 Nm will freely drive a 10-centimeter self-tapping screw into the wood.
Solid home models are equipped with a special limiter, which is installed immediately behind the chuck. The operator can coordinate the force of the tool by twisting this ring. In addition, it also protects the device from premature wear.
It is expressed in terms of the number of revolutions per minute produced by the equipment. Usually, the adjustment is set electronic, i.e. the harder you press the trigger, the higher the speed of the device will work. Thus, the denser the material into which you want to screw the self-tapping screw, the harder you need to press the hook.
In the device, this parameter is characterized by the technical speed:
A chuck is an element that holds a drill or screwdriver. They are of the following types:
Such features are usually equipped with branded models. These include:
It is always worth remembering that the presence of additional functionality in a screwdriver will definitely affect its price upwards.
Naturally, a screwdriver should be suitable for a potential buyer in terms of price, functionality, and sit comfortably in your hand. However, it is worth paying attention to the technical side of the matter, that is, the characteristics of the tool itself.
The main criteria to be taken into account are:
Still, the brand in construction equipment plays an important role. Well-known and well-established brands offer high-quality tools, have reliable warranty service, but are also not cheap. An analysis of the Russian market in this area suggests that Russians prefer to use foreign-made samples.
The top three for 2022 are as follows:

The choice of a screwdriver will always depend on the purpose of its use (professional daily work or on an occasional basis) and on the financial capabilities of the buyer. Most construction experts still recommend buying tools from retail stores rather than relying on pseudo-savings when shopping online.Buying at retail involves inspecting and checking equipment directly "on the spot", which will eliminate future issues of performance and functionality of the purchase. At the same time, professionals prefer to stop at foreign-made tools, having little confidence in both domestic and Chinese manufacturers.
