Drill clean, chip-free holes in the hardest materials with our diamond drill bits and diamond core bits. The diamond-coated edge grinds through porcelain tile, glass, natural stone and ceramics that would shatter under a standard bit.

For best results, run them at a slow speed with plenty of water to keep the diamonds cool and prevent cracking. Ideal for tile setters, glass installers and stone fabricators.
