Diablo 5/16 In. x 3-1/2 In. Carbide Tipped Glass, Tile & Stone Drill Bit

Diablo's next generation Hard Tile & Stone Carbide Tipped Drill Bit range provides faster starts and up to 10X longer life in tile, stone, and glass versus standard glass and tile drill bits.

Optimized with a unique brazing and hardening process, the carbide tip extends life and productivity, allowing users to drill fast, accurate holes.

The multi-ground carbide Grip Point tip design allows for aggressive starts that produce clean holes when drilling into hard materials.

The 3-Flat Shank provides extra stability by eliminating spinning in the drill chuck.
