Power tool kits with drill driver

Drill driver

— tools that combine the functionality of a drill and a screwdriver. Such "hybrid" devices are extremely popular nowadays due to their versatility. Switching between drilling and twisting modes in them is carried out by replacing the cartridge, and also, in most models, by adjusting the torque. At the same time, it should be noted that compared to traditional drills, the efficiency of such units when drilling is rather low, they are not intended for high loads, hard materials and large drilling diameters. This is due to the fact that in order to achieve high power, it would be necessary to increase the dimensions and weight, which would significantly complicate the use in the format of a screwdriver.
