Had ordered me this machine. Unfortunately, both chuck ran out of round, as the wobbled my drill. Lies to the naked eye even without drills, both the SDS and in the other tower. The part of the drill, the drill chuck to be placed, looked okay. So I sent the machine back and again a similar order with the hope that everything is OK with this. But, unfortunately, exactly the same as in the first machine, and, moreover, I was ordered to ascertain already sparking in the new machine do not know if this is normal. Would otherwise be a good machine but you do not want to keep these shortcomings and send them back even pity. Will look around at Bosch because I envision the 2-28.
