Bosch 3/16 in. x 3 in. x 4 in. Blue Granite Turbo Carbide Hammer Drill Bits for Concrete, Stone and Masonry Drilling (25-Pack)

Bosch Blue Granite Turbo bits begin with the aggressive holds achieved on the PowerGrip shank. Flat tabs that extend from the shank are designed to catch between the jaws of power tool chuck systems. That means the bit is easy to chuck in the tool and the bit won’t slip. The tip of the Blue Granite Turbo bit is Bosch carbide, diamond ground for precise starts to avoid scratching and skating in tile and hard stone.
