A real owner, and even more a summer resident in his business, cannot do without a reliable assistant.

This Chinese model is so easy to use that many have “collaborated” with it for many years. For this battery device, there are no barriers, of course, at the household level. He quietly twists / unscrews:
screws;
bolts;
self-tapping screws.
However, it can also be used as a drill. With it, you can drill holes of different diameters. The drills easily penetrate any kind of hard surface. Moreover, the light weight of the tool will allow the summer resident to manage it skillfully even in hard-to-reach places. All these privileges are possible only due to the unique characteristics of the screwdriver from China.
Powerful, therefore, fast

The ergonomic shape of the elongated holder allows you to firmly hold it in your palm. This also contributes to the rubberized grip, which has a triangular shape. Such an insert increases the coefficient of adhesion of the material with the hand. At the same time, among the technical characteristics of the instrument can be noted the following features:

Protection system The device has built-in elements that prevent overheating of the device. In addition, they protect the instrument from overload as well as the complete discharge of the battery.
