Hand drill

One of the most popular electrical construction tools used by repair men is an electric or manual drill. If it is present on the farm, this is very good!

Drill is a complex electrical -type construction tool that performs a large number of functions and works. At the same time, the issue of buying a drill is also difficult, since today there are a lot of different types and purpose of electrical manual drills. Everyone here is not just confused, but at all does not want to buy a drill for himself! And therefore, experts recommend that you first familiarize yourself with the types of drills and information about them.

Firstly, it is necessary to estimate the type of work and its volume, in which the drill will be used. Next, you need to find out how the drill will be used, with what duration. After all, you yourself understand that in addition to direct drilling holes, the drill is also used in other works. For example, it is convenient to use it for mixing various semi -liquid and dry mixtures, for screwing screws and t. P. If you add grinding nozzles to the drill, then it will turn into a powerful grinding machine, which will not be inferior to an original analogue.

Then we determine with the load that the electric drill will withstand, as well as with the duration of its operation. These factors will directly affect the power of the drill and its motor.

So we approached the choice of a class of an electric tool – household or professional?
