The Milwaukee 3-Flat Secure Grip hammer drill bit drills faster and lasts longer. 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. Reinforced flute geometry increases bit stability. Carbide tips extend performance in masonry applications.
Nickel plated for fast, smooth performance. Carbide tip can be used for rotary drilling applications also for deep drilling. Slow spiral for quick and easy debris removal; 7/16" and larger drill bits have reduced shanks.
Bosch BlueGranite Turbo carbide hammer drill bits deliver long life and speed over standard masonry bits, resulting in increased on-the-job productivity. This impact rated bit has been redesigned with a hex shank and is designed for use in today's higher torque hammer drills and impact drivers. The bit features and upgraded four-grind head, delivering additional cutting angles for faster drilling. The multi-grind centering tip also provides for precise starts in masonry, block and concrete. Milled U-flutes with deep cut spirals delivers fast dust removal. Bosch made carbide delivers outstanding durability under heavy loads.
Bit will fit all hammer drills with 3-jaw or Jacobs chuck and features a chrome vanadium shaft through hardened to 50-53HrC, shot-peened, double-tempered finish, flute geometry removes dust from the hole quicker, copper braze material gives high heat resistance. All tips made to ANSI specifications.
Rock carbide tip maximizes carbide surface contact for longer bit life; four flutes clean debris out for fast, efficient drilling and three flats on shank eliminate bit slipping in chuck.
Use to power through masonry, concrete, rock, and more with DEWALT Hammer Drill Bits. Featuring rock carbide tips that maximize surface contact for extended bit life and a four flute design that cleans debris while you work. Three flats on the shank eliminate bit slippage. Two cutter carbide tip maximizes carbide surface contact for longer bit life.
