Review: Works Great, Keep it Cool with Water, Pilot Bit Not Particularly Useful on Hard Surfaces. - The core drill cut a clean hole in my granite countertop without trouble. The pilot drill that comes with the core drill is high speed steel and is not intended for hard surfaces like granite. This should be listed in the description but since I did not need it I felt 5 stars was still appropriate. The way this drill is used is to start at an angle and slowly straighten the drill up. This creates a nice channel (kerf) for the drill to follow and I did not have any wandering. Keep the drill wet which provides cooling and tends to float the cut material out of the cut. I just used a wet sponge and periodically dripped water into the cut. Pull the drill out and spin in water to remove grit and cool the bit. I only needed one hole so I don't know about longevity, but it certainly worked for me. I would buy this again. Just don't rely on the center pilot bit unless you are drilling something relatively soft.
Review: Worked perfect for my repair. - This was a one time repair. If the saw I chose at desertcart cuts one hole properly, I’m happy! “I’m happy”. This 1.5” saw did great! Be sure to read included instructions about pilot drill use and saw cooling. It states to remove the pilot drill after the saw has started the cut. This could be a challenge to keep saw from hopping out of hole location and damaging area next to the started circle. Suggestion, clamping thin wood with same hole cut in it over the proposed hole location may keep saw where it belongs while drilling. My story if interested. I had mildew at bottom of wall under the diverter in the shower. Bleached it and came back so time to investigate before we got sick from mildew. I lucked out and chose exact (6x8) tile to remove for the inspection and repair. There was a slow constant drip drip at the diverters plumbing connection at hot water side. Made that plumbing repair and then dropped bag of Damp-Rid on a rope into the wall until it hit bottom. Got considerable water in the bag over 2 week period. New bag, same, no more water and no more mildew appeared, time to close it up. I made a cardboard template where to cut hole in a tile saved from home construction, then marked the tile on tile back-soft side. See pics. The cut through the hard glaze was quick, I doubt saw got too hot so cooling the saw probably wasn’t necessary in my case but made cut in container of water anyway. Drilled from the soft back side. Some minor chipping occurred, perhaps placing tape over the glazed side would help.
