I recently bought an under-counter kegerator and need to have some holes drilled in the granite countertop for the tap. The template and mount has 1.75" hole in the center (to run the beer lines) and then 4 small 3/8 holes around the center hole where bolts are placed to secure the tap down to the kegerator.
I called our granite installer and they want $200+ just to come drill the holes. Looking online, you can get Diamond Core Hole Saw Bits for $40, and smaller diamond bits for the screws for around $10. Obviously this is cheaper, but can a my standard corded Rigid drill (not VBR or hammer) handle this? Wonder what the risks are in chipping the granite? Some people recommended putting a ice cube in the bit to keep it cool and emulate a wet drill. What would be a technique to get the bit started, so it does not move when making its first cut into the stone?
Any other tips?
