Hammer Drill Bits

Milwaukee® 3-Flat Secure-Grip™ Hammer-Drill Bits drill faster and last 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”.

  • Reduced slipping: 3-Flat Secure-Grip™ shank holds the bit firmly in the chuck
  • Faster drilling: Reinforced flute geometry increases bit stability
  • Longer life: Carbide tips extend performance in masonry applications
