Diablo DMANSP1010 Drill Bit, 1/8 in Dia, 3-1/2 in OAL, Hex Shank

Diablo's next generation hard tile and 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 hex shank provides extra stability by eliminating spinning in the drill chuck.
