She drills full-bodied and silicate bricks with great tension, you understand that there is not enough power. Foam blocks, aerated concrete, dense wood - this is quite a material for her. It comes across that it is harder, the drill begins to heat up. If pressed, it can jam tightly. It also infuriates that the handle turns (maybe only I have such a marriage, until I went to the service). I tried to drill 16 mm holes in a brick and began to hit the cartridge with a drill that heats up wildly. Too "capricious" drill, even for purely domestic work, although expensive, but a little useless.
