Had promised me a lot more of the Bosch 750W -Power. I had to drill 10 St. 10 mm holes in concrete slabs. However, after about 5! Holes was the chuck so hot that the plastic lining dissolved, the grip slipped and chuck the drill no longer held, even though I had already placed several breaks. I still have an old Bosch machine with only 320 watts and chuck that is good in principle better. This PSB 750 RCE is recommended at most for a few smaller holes.
