Description

Maximize Your Productivity with 5X Longer Life and 2X Faster Masonry Drilling

The Bosch HCBG27T BlueGranite Turbo™ Carbide Hammer Drill Bit is engineered for professionals who demand speed and durability in the toughest materials. Featuring a massive 1-inch diameter and a 12-inch overall length, this bit is perfect for creating large-bore holes for conduit, piping, and heavy-duty anchors in concrete, stone, and masonry. Designed to outperform standard bits, the BlueGranite Turbo series delivers five times the service life and twice the drilling speed, ensuring you spend more time working and less time changing out dull equipment.

This impact-rated bit has been precision-engineered with an upgraded four-grind head, providing additional cutting angles for aggressive material removal. The multi-grind centering tip allows for surgical precision when starting holes, preventing bit walking on smooth surfaces like block or brick. Transitioning between tools is seamless thanks to the 3/8-inch hex shank, which provides a secure, non-slip grip in modern high-torque hammer drills and impact drivers. Milled U-flutes with deep-cut spirals further enhance performance by rapidly clearing dust and debris from the hole, reducing heat buildup and extending the life of the Bosch-made carbide tip.

Key Features

  • Extreme Durability: Delivers 5x the life and 2x the speed compared to standard masonry bits for maximum on-the-job productivity.
  • Impact Rated Hex Shank: Redesigned for versatility, allowing use in both impact drivers and high-torque hammer drill/drivers.
  • Four-Grind Head: Features two additional cutting angles for faster drilling speeds and significantly longer bit life.
  • Precision Centering Tip: Multi-grind carbide tip ensures accurate starts in brick, masonry, block, and concrete.
  • Efficient Dust Removal: Milled U-flutes with deep-cut spirals evacuate dust quickly to prevent clogging and overheating.
  • Bosch-Made Carbide: Proprietary carbide blend provides outstanding durability and strength under heavy loads.
  • Robust Build: Specifically designed to withstand the high-stress vibrations of impact applications.

Pro-Tip: When drilling deep holes with a 1-inch bit, use a "pecking" motion by occasionally pulling the bit partially out of the hole while it is still rotating. This allows the deep U-flutes to eject any packed dust, preventing the bit from binding and keeping the carbide tip cool for a much longer service life.
