  • drill hole in granite kitchen sink

    What type of drill bit do I need to drill a 1 1/2 inch hole in a Blanco SilGranit kitchen sink? Thanks

    a diamond core drill lubricated with water would be ideal. second choice a silicone carbide hole saw. I saw this on the home tv network. drill through a synthetic sponge several times and leave the sponge up inside the hole saw fill the sponge with water then drill your hole at a low speed like with a cordless drill

      I would strongly suggest that rather than attempt an unproven method you should contact your dealer or the manufacturer directly to see what they recommend otherwise you would risk voiding your warranty.

      Usually if you just imput the manufacturers name on the "search" line on your web browser you can find a home page for the manufacturer. Once you locate that you can usually find a tab marked "contact us" and you would be able to email them directly.
