The 5/16" x 10" x 12" Milwaukee® 3-Flat Secure-Grip™ Hammer-Drill Bit drills faster and lasts longer than others on the market. The 3-Flat Secure-Grip shank fits in all 1/2” three-jaw hammer-drill chucks and maintains unyielding bit hold with heavy torsional loads. Designed especially for conical anchor, concrete screw, nail-in and hollow wall anchor applications, the bit provides superior performance through its reinforced flute geometry and carbide tip design.
Milwaukee offers a complete range of 3-Flat Secure-Grip Hammer-Drill Bits in diameters from 1/8” to 1”with lengths up to 18”.
