Agreed! Also keeping the bit cool will allow the bit to hold the edge longer. So a little water dripped on the hole while drilling will help.It'll be easier than you think. I just drilled an 1-1/2" hole in a finished granite vanity top fairly easily. Took a little elbow grease but was easier than I expected. A quality bit is key.
I definitely would not use putty, the oils in putty will stain the granite, some plumbers still don't know this and they get staining around fixture mounts. Duct tape works betterI've done it and used putty as a dam to keep a little bit of water on the cutting area. Probably overkill, but the bit is still good. Normally I leave it up to the stone guys.
Oh, and a hammer drill may have some unwanted results.
You see why I tend to leave it to the stone guys? I think I'm doing myself a favor and I'm just lucky I didn't f#$# the whole thing up!I definitely would not use putty, the oils in putty will stain the granite, some plumbers still don't know this and they get staining around fixture mounts.

I asked my plumber and granite guys about that and they said to stay away from it so I have.Get non staining putty.
ya know what, I think I take back my previous statement. If I needed 1/4" holes in a granite top, I would use a 1/4" hole saw bit.Patsfanindallas said:you say that as if they don't make 1/4" core bits. That being said, I guess it could be a solid bit just the same.
