Rotary percussion bits made of chrome vanadium shaft through hardened to 50-53HrC. Shot-peened, double tempered finish reduces breakage, copper braze material gives high heat resistance and flute geometry removes dust from the hole quicker for fast drilling and long life. Used in applications such as rotary drilling in concrete, brick and masonry.
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.
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.
Negative carbide tip for rotary and percussion drilling. All sizes 3/16" and larger have 3 flats on the shank so that the chuck gets a better grip on the bit. Wide flutes quickly move out debris and dust. For drilling brick, stone, concrete, ceramic and damp and dry masonry work.
Positive tip geometry for best rotary drilling efficiency. All sizes 3/16" and larger have 3 flats on the shank so that the chuck gets a better grip on the bit. Wide spiral flutes efficiently remove dust and debris, from the cutting area. Used in applications such as drilling in damp masonry work, brick, cement, tile, slate and cinder block.
Carbide tip minimizes wear and extends the life of the bit. Used in applications such as drilling in brick, cinder block and tile.
Designed to fit in all 1/2" three jaw hammer-drill chucks. Reduces the possibility of the bit spinning in the chuck during heavy torsional loads. Flute geometry provides dust and debris removal. Self-centering tip.
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.
