Excellent for making clean and precise holes on glass or ceramic and considerably extending drill bit life. Perfect for drilling glass, tile, porcelain tile, ceramic tile, brick, and stone These glass hole saw set along the drill bit facilitate the entrance of cooling water and escape of chips and other particles from drilling.
