Our tile and natural stone drill bits deliver up to 2x life in granite, stone, ceramic tile and glass. Hammer mode capability provides faster drilling speeds when drilling natural stone tiles, like granite and marble. Equipped with an aggressive eight grind carbide head, these bits deliver up to 20% faster drilling. These bits feature reinforced tips that protect the carbide head, providing the durability needed for use in hammer drill mode. Milwaukee® tile and natural stone bits can be used in drill only mode or hammer drill mode and we don't recommend them for porcelain tile.
