I have put the impact drill with intent in quotes. Have decided to use one of the strongest of the Home Series series, because I had to drill a few holes in concrete floors and ceilings and to also in a few thin metal support. The first impression of the machine was robust and stable.
That was unfortunately the good points.
The keyless chuck broke up frequently during drilling of thin metal beams (max 1mm thick, not stainless steel), I had here often tighten the keyless chuck because the drill has always caught in the carrier.
When concrete drills then it started. The clout is ridiculous, I felt a long time needed by about 5cm deep to drill with a concrete drill 6 in the concrete. Those present have had the same feeling. And now the sad, without exaggerating, I have a total of approximately 12 holes drilled in concrete, 4 back to back. The drill was caught or anchored in the keyless chuck, I would even argue that the drill is "merged" with the dust in the keyless chuck. It was not possible to solve the food, not even by my 2 colleagues.
I write this review after I bought a comparable Makita machine, this works fine and beats in the concrete, like butter. Had the machine as a defect Send back unfortunately. Therefore, I can give a maximum of one star. Maybe I got a sunday device, but I have the engine really requires at the weekend and something I do not want to see use after a few holes and a day.
