I had here who have failed at the holes to be drilled in the house several projects. The reinforced concrete was no getting who gekostest me some drills (drill burns). I had already been thinking about a new, more powerful impact drill or even drill hammer. As an alternative then I got luckily still trying with quality drill bits to mind. All work already begun could be accommodated in a start to end, semi-finished holes I have since not. I had, considering the old drills, an enormous Verl shit on the drilling heads of the expected, however, has not been set.
I would recommend this product around and the slightly higher price seems justified.
