Review on Bosch HS1911 SDS Max® Hammer Chisel by Hesham Peltier

This is a quality bit that will break through bedrock with no problem here in the central USA. The only reason I didn't give it 5 stars is that the chisel could have been made longer which in turn would mean less flexibility in using the tool. This drill bit was used after drilling pilot holes in bedrock and then reaming the rock. in between. Fast and easy. Changing bits is quick because it's an SDS-MAX bit (so it won't work with non-SDS-MAX bits). Just apply some lube and get to work!
