    Honolulu,, Hi.

    @Kevin6 or any one can help.
    I need to cut 100 holes in 1¼” granite with diamond hole saw. I’m wondering how many holes one hole saw will cut? Kevin could please direct this to the right person? These blades are expensive and I need to know how many I will go through so I don’t loose my but on blades.

    What size of hole? Are you cutting indoors or out?

    That’s what I was thinking. Are they going to have the 96mm spacing?

    On the flip side, put a dept ring on that new demo bit for your new toy and just pound out 100 holes. Then find some slacker to sand the holes for you. Win, Win.

    That many holes you would have to go wet or you are going to drop a mint on hole saws.

    What kind of drill will you be using? I’ve used a diamond bit to drill some holes in tile…can’t imagine 1¼” granite! And 100 of them??? Yeah I’m curious too!

    The counter top shops I have seen drill for faucets on site use a right angle grinder with a Diamond core bit. They drill dry.

    To keep the dust down, they set a roll of 2″ painters tape where the hole will be and place the bit in the center of the roll. It keeps a significant amount of the dust right down on the counter where they can brush it away.

    I have a 2″ core bit with an adapter to fit my SDS Max demolition hammer. I have used it to drill for popes through block walls.

    Honolulu,, Hi.

    Shit i forgot to hit the button to get a response to this!!! It’s a high rise building and a lot of kitchens to set. We will be cutting the granite tops to length and drilling for the plumbing. So yes the wet hole is what I’m thinking and a ½” drill and the diamond hole saw. Maybe a small Ridgid wet vac.? @kevin can you direct this to the right person.

    This is good stuff! The best I’ve gotten so far!

    That is cool…I have used one I picked up at HD and it has drilled lots of holes in limestone with no issue — wet. I know limestone is much softer than granite, but it seems like it will last for a long time. The grind option sounds cool too.

    Ok, Dirty and crew. I checked with our drillng expert . This is a lot of holes in an abrasive material, so at this depth, you would average 3 holes per cup. That should help work that into your quote.

    A quick word – go with high end bits for a job like that. I bought a set of cheapies and they were worn after a single hole without any diamond material left, and that was drilling wet in porcelain.
