Review on Impact drill BOSCH GSB 13 RE (0 601 217 100), 600 W blue by Wiktor Kosiorek ᠌

Drills well, and the cartridge is very convenient. Clamped into it and drills on concrete, exposing so that they would not beat the norms. But it's hard on concrete. Overheats. Perhaps the impact mechanism has already been demolished, but rarely drilled on concrete. In general, there is no puncher function in it, it crumbles a soft wall. And if a monolith where a good mixture of concrete is very difficult for him, you will have to buy a perforator.
