Usually, every person who carries out even minor repairs at home has a drill in their arsenal of tools. Indeed, without this power tool , it is impossible to carry out repairs both outside and inside the house.

When performing small tasks, whether it's repairing furniture, hanging curtains, installing shelves, or removing old screws, a drill/screwdriver will definitely help you out in all these cases.

Today we will tell you how to choose a drill driver that best suits your ideas.

Where is a drill driver used and how does it work?

This tool is actively used by both country house owners and those who live in their own house or apartment. No matter what work is being done - construction or repair, you will definitely need to use an electric screwdriver .

How does it work?
The electric motor rotates at a specific speed;
A planetary gearbox transmits power to a spindle equipped with a chuck;
Has the ability to adjust rotation;
The electronic control system is equipped with a device on/off button, as well as a reverse rotation function;
A battery is usually used as a power source. Therefore, this type of device is convenient to use in places where there is no electrical power or in places where a power cord cannot reach.

Now we will list for which work it is advisable to use a drill screwdriver :

Making and removing various screws or bolts;
Wood, as a soft material, is ideally drilled with screwdrivers;
The device can also be used to drill metal surfaces;
It is quite possible to cut metal materials (and not only) with the tool.

Torque and speed indicators

Torque determines how much force a screwdriver uses or how much force it exerts against a load. In everyday life , electric screwdrivers with a torque of 10 to 15 newton meters are used.

Professional models can handle torques of up to 130 Newton meters, which allows them to drill very hard materials. The motor shaft of such devices produces 1200-1300 revolutions per minute, while household models - 400-500 revolutions per minute.

Depending on the torque, the length of the screwdriver and its diameter are selected. Thicker and longer screwdrivers can be used in more powerful models. In addition, these devices can be used when working with sufficiently hard materials.

Screwdrivers differ from other power tools in that their torque can be adjusted.
