the drill is suitable for drilling wood and brick, but the seller and instructions also talk about concrete. So it is written 13 mm in concrete maximum. Well, OK! I tried a dozen drills into bricks, they are well drilled into concrete, even with a blow - not very well. You can still see the drill only on brick and wood, although it looks like it is fully assembled (with a handle, a drilling depth limiter) just WOW. In the work I felt the beating of the cartridge several times, but for now I write it off for the period when I experimented with concrete walls. In a word, I have a double impression of the instrument. It seems to work, but as if the promised functionality is not in it.
