A screwdriver, in essence, is a substitute for a conventional screwdriver with the only difference that it works without the use of human force to rotate. With its help, they perform the same functionality, only now 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 it is necessary to screw / unscrew dozens or even hundreds of bolts. However, the scope of the screwdriver is not limited to one screw-in of bolts. By inserting a special drill into it, they can drill holes in wooden surfaces, plastic and even thin metal. Professional devices of this type of tools will also master bricks and concrete. In recent years, the most widespread are screwdrivers powered by mobile batteries, and they have almost supplanted devices that operate on the mains.

Unlike network devices, they are more maneuverable 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.
Battery for them are:
This parameter shows how hard the tool is to tighten the bolt, or how much force is required when drilling in order 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 stop, 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 the number of revolutions per minute produced by the equipment. Usually, the adjustment is set electronically, that is, the harder you press the trigger, the more speed the device will operate. Thus, the denser the material into which you want to screw the self-tapping screw, the more you need to press on the hook.
In the apparatus, this parameter is characterized by the technical speed:
The chuck is the element that holds the drill or screwdriver. They are of the following types:
Brand models are usually equipped with such capabilities. These include:
It is always worth remembering that the presence of additional functionality in a screwdriver will certainly affect its price upward.
Naturally, a screwdriver should be suitable for a potential buyer in terms of price, functionality, and sit comfortably in the hand. However, it is worth paying attention to the technical side of the matter, that is, the characteristics of the instrument itself.
The main criteria for special attention are:
Still, the brand in construction equipment plays an important role. Well-known and well-established brands offer a quality tool, have a reliable warranty service, but they 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 2024 looks like this:

The choice of a screwdriver will always depend on the purpose of its use (professional daily work or from case to case) and on the financial capabilities of the buyer. Most construction experts still recommend purchasing tools from retail stores, rather than trusting the pseudo-economy when shopping on the Internet. Retail purchase involves inspection and testing of equipment directly "without leaving the checkout", which will eliminate in the future issues of operability and functionality of the purchase. At the same time, professionals prefer to dwell on foreign-made tools, having little confidence in both domestic and Chinese manufacturers.
