Review on Diamond Cutting Tools for Porcelain Countertop Bathroom Installations - Hole Saw Kits & Accessories by Don Pintac

I have been very pleased with the quality and performance of this hole saw. I had never cut marble or stone for faucet holes before so I didn't know what to buy. It was a great product at a great price, did the job well (tip: use water to cool the blade) and after two cuts I think I should have no problem cutting other stone surfaces when the time comes . I can't say how long the diamond hole saw will last, but I'm very satisfied and all cut surfaces look like new.
