Tile Drill Bits for Porcelain, Ceramic & Stone

23 products

Diamond tile drill bits for clean holes in porcelain, ceramic, granite, marble and slate without cracking the tile. The range covers dry-drilling bits for cordless drills and angle grinders, wet-drilling bits for the hardest vitrified porcelain, and sizes from 5mm fixing holes to 130mm waste outlets.

Choose by shank first: M14 bits fit an angle grinder and drill fastest, hex and round-shank bits fit a standard drill. Then pick the size; drill guides and cooling gel are in the Tile Drilling Accessories collection.
