I have an undermount sink mounted to a 3/4" granite countertop. I would
like to drill a hole in the granite to accept a hand sprayer. I observed
the guys installing the granite when the house was built, and it doesn't
seem like a big deal to drill a hole. I am a capable DIYer.
My thoughts are to tape some plastic down to the counter to act as a water
dam, irrigate the surface with plain water, and drill with a 1/2" drill, but
what kind of bit to use? Is it as simple as it would seem, or should I
break down and hire a granite installer?
