Received 2 days in advance on the prediction, I could use this bit on my classic puncher "SDS Plus" also bought SDS plus for this purpose adapter (guide strand and more too). Everything bought on Amazon. The hole in my slab is already well drilled before the end of the weekend. I had taken care to have a length of 100 mm adapter + another length 450 mm in order to comfortably break without my puncher touches my slab during the last rotations.
