Review: Excellent Tool - Bought to drill a 1/2" hole in a polished granite kitchen countertop to install a faucet for an under sink water filter. Diamond grit edge cut smooth and steady, and it removed a solid plug of granite that was just the right size. The bit showed no appreciable wear when done, and should perform well for a while. My basic DeWalt cordless drill/driver managed the job just fine. Important to follow instruction diagram to start bit at an angle to create a crescent shaped cut on the polished surface to guide the bit before tilting it up to vertical or else it may wander. Also good to have a water bottle handy to wet the bit and the cut as you proceed. This serves to keep the bit cool and to stop flyaway dust. I highly recommend this product and I would buy it again. Review: Exactly what you need from a brand known for quality. - I was very pleased at the performance of the bit will drilling through tile that would have been impossible to replace due to its size. Just start the hole on a 45 degree angle then gradually go perpendicular to the surface. Use patience and a slow speed with plenty of water spray to flush and cool the bit. Don't worry about the core plugging it will easily push clean with a small nail since there is a slot in the side of the bit. Clean often while drilling. 4 holes showed no change in performance. Buy a brand you can trust. ## Features - VACUUM-BRAZED DIAMOND GRIT CUTS FASTER AND LASTS LONGER - SEGMENTED TEETH REDUCE DEBRIS AND HEAT - REMOVE MATERIAL PLUGS QUICKLY, EASILY - ONE IN.
