Milwaukee 48-20-8985 Drill Bit, 1/2 in Dia, 3-3/4 in OAL, 1/4 in Dia Shank, Round Shank, Carbide

Our glass and tile drill bit features an exact start tip for clean holes and minimal bit walking in glass and ceramic tile. Engineered with sharpened carbide, Milwaukee® glass and tile bits provide faster tile drilling than standard glass and tile bits. We've designed these bits with a reinforced carbide head for increased durability when high-speed drilling into tile and glass. We've specifically designed these bits for drilling holes in glass and ceramic tile with drill drivers only. We don't recommend these bits for use on porcelain tile.
