I need to enlarge the faucet holes in a granite countertop for a customer. They look like about 1-1/8″ and need to be more like 1-3/8″. Anybody suggest a method and tool to go about this, or better to leave it for someone else?
Thanks,
Bob

In older homes like these, the main remodeling goal is often a more welcoming, more social, and more functional kitchen.

Diamond hole saw. Carbide might even work.
First take a scrap board or plywood, and drill a hole the same as the OD of the diamond hole saw you will be using. Then clamp or stick that template over where you will be drilling. It's just needed until you get the hole saw started. Once it makes it's own groove, you can remove the template.
Use a sponge with some water to cool/lubricate the cut. Don't rush.
BTW, don't use the diamond saw on the plywood template. Use wood bits.

I was faced with a similar situation except that I had to enlarge the hole toward the sink to accommodate a larger handle. I used a 1/8" carbide to drill a series of holes on the side where the space was needed. I then took a small chisel and CAREFULLY broke out the pieces remaining between the drilled holes. I then took a rasp to smooth the rest of the spaces between the holes I had drilled. (I had to enlarge the 1 1/2" hole about 1/4" to get the clearance I needed on the backsplash.)
I am not sure I would do this again as, as you know, granite is treacherous to work sometimes. I worked very slowly and carefully and was very LUCKY.
PS: After I posted I saw Pete's response. Ignore mine.
