Use the QEP Diamond Hole Saw Kits to drill holes when installing bathroom fixtures on various tile surfaces including the hardest porcelain, ceramic, marble and granite. These drills feature a metal saw with diamond grit edge for long lasting use, limited wear, faster cuts, less dust and less chipping. In addition to the hole saw, each kit contains adhesive pads, a water cooling system and drill guide. This hole saw must be used with the water system to keep it from overheating and must be used with a cordless drill.
