SANLEETEK 10Pcs Diamond Drill Bits Set - 1/4 Inch (6mm) Hole Saws For Tile And Stone

About This Product

DIYers and professionals, these SANLEETEK diamond drill bits are seriously tough for drilling through hard materials! The set includes 10 identical 1/4 inch (6mm) diameter bits that are perfect for creating precise holes in tile, marble, granite, ceramic, porcelain, and quartz. The vacuum brazed technology means the diamond grains are securely bonded to the surface, giving you longer life and better performance. The spiral groove design helps remove debris as you drill, preventing clogging and overheating. You can use them dry or with water for cooling - though water will definitely extend their life. They work with standard hand drills or bench drills, and they recommend running them at least 2000 RPM for best results. The round shank fits securely in most chucks without slipping. Seriously, if you're installing bathroom fixtures, doing tile work, or any project that requires clean holes in hard surfaces, these diamond drill bits will save you from cracked tiles and frustration. Way better than trying to use regular bits that dull immediately on hard materials!
