Review on Diamond Hole Saw Core Bit: The Ultimate Tool for Precision Cutting by Ronald Ingram

Cuts great. My only complaint, not really a complaint. My own silly mistake, unless. discovered it too late. I believed the markings and started drilling, only to find out that it can't cut all the way through the stone no problem since i didn't have a pilot hole to drill all the way through i started micro cutting the core cut the core far enough to try again success Then, after the dry install, my 3" PVC pipe didn't fit in. Even though the packaging says 3 1/4", my 3" pipe didn't fit. Now I understand the mislabeling. It happens. But it was super disappointing. So buyers beware. MEASURE THE BIT YOU GET. Just to be safe (and smart). :-(That's sad. It's a great drill. Rigid. Still in good shape despite my beginner hands and cheap masonry drill.
