An impact drill with lousy impact power is nonsense, especially for Bosch. Brick, foam blocks and wood drill normally, as it should be "German quality" - quickly, smartly, without noise and dust. But there are problems with concrete. The drill makes a small hole and spins in one place, if you start to press, the drill buzzes and heats up. This is despite the fact that you drill with an 8 mm drill, and the instructions say up to 13 mm in concrete. The reverse also began to act up after 10 days of operation. Disappointed.
