The impact drill is doing what it should: easily drill holes in various materials. I've drilled into wood, stone, metal and concrete. To this end I have made myself Bosch drill. The engine is very powerful and that you have a conventional drill chuck (ie with key) has, me does not bother, because many cheap machines the keyless chuck is the Achilles' heel: The drill dissolves, no longer rotates and you always have to re-tighten. That does not happen here. However, it is not unwieldy admittedly compared with other machines pretty hard but not (yet).
