Review on Enhance Your Cutting Precision with the Lenox Tools 1211110DGDS Diamond S 10DG by Anthony Heinrichs

I bought this to drill a 1-1/2 inch diameter hole in a granite countertop to install a hot water dispenser . Manufactured to be typical of Lennox hole saws and the barrel is long enough to be used on a worktop. He carefully walked through a thick granite slab. You need to keep it in a cool place to avoid damaging the bond that holds the diamond abrasive in place. to the metal tube of the hole saw. The easiest way to do this is to make a circle of plumbing putty about 2 1/2" or 3" in diameter and about 3/8" or 1/2" deep and fill it with water. Then start cutting by tilting the drill about 45 degrees so that it starts cutting in an arc. Slowly tilt the drill 90 degrees to complete the cut. Do a YouTube search for "granite countertop hole" on YouTube to find good videos on how to do it. Use a cordless drill with a good battery and be patient. Depending on the thickness of the stone, it will take 5 to 10 minutes. Keep the water in the putty circle and remember that as you cut through the stone and the saw begins to penetrate, the water will start to flow out.
