The worst thing is drilling holes in a client’s expensive granite countertop; even a chipped edge means a pay cut. Using this diamond drill bit, the edges are smooth and clean, with absolutely no chipping. Yesterday, I drilled eight holes in one countertop, and the drill bit is still like new. I estimate drilling 50 holes will be a piece of cake.
