I bought this bit to use in my Milwaukee 5426-81 SDS-MAX Rotary hammer. I needed to drill four holes, each 12" deep, into a concrete wall. We vacuumed out the debris from the hole(s) every inch of progress. We were able to drill all four holes without any binding or stalling, and the bit performed perfectly. I snapped a few photos of the bit after the job, so you can see that there's almost no wear on the bit after 48" of concrete. . You won't have any trouble with this one. It's a beast!

      drilled 10 -12" holes in granite, then used dexpan to break up the ledge for removal in my yard. this bit worked fast and despite the fact that I used the bit first as a demolition hammer bit for an hour to loosen the fractured stone. Bit is still very workable.
