Description

Drill Deeper and Faster with BlueGranite Turbo Precision

Reach further and finish faster with the Bosch BlueGranite Turbo™ 1/4 in. x 12 in. Carbide Hammer Drill Bit (HCBG08T). Engineered for deep drilling applications, this extra-long bit delivers up to 5x longer life and 2x faster drilling speeds compared to standard masonry bits. The advanced four-grind head provides additional cutting angles for aggressive material removal, while the multi-grind centering tip ensures precise, walk-free starts in concrete, block, and brick. This makes it an ideal choice for installing long anchors or drilling pass-through holes in thick masonry walls.

Designed for secure power transmission, the bit features a Power Grip round shank that provides a superior hold in standard three-jaw hammer drill chucks, reducing slippage during high-torque applications. The milled U-flutes with deep-cut spirals efficiently evacuate dust from deep holes, keeping the bit cool and preventing binding. With its robust, Bosch-made carbide tip designed to withstand heavy loads, the HCBG08T offers the durability and performance professionals rely on for their toughest jobs.

Key Features

  • Extended Reach: 12-inch overall length allows for deep drilling and pass-through applications in thick masonry.
  • Superior Speed: Delivers 2x faster drilling performance than standard masonry bits for increased productivity.
  • Longer Life: Upgraded build provides up to 5x life in tough materials like concrete and block.
  • Secure Hold: Power Grip round shank ensures better grip in the chuck to prevent slippage.
  • Precision Starting: Multi-grind carbide centering tip prevents bit walking for accurate hole location.
  • Advanced Cutting Head: Four-grind head delivers two extra cutting angles for faster material breakdown.
  • Efficient Dust Removal: Milled U-flutes with deep-cut spirals quickly clear debris from deep holes.

Pro-Tip: When using a long drill bit like this 12-inch model, it is crucial to clear the dust frequently. Withdraw the bit partially from the hole every few inches while drilling. This "pecking" motion allows the flutes to eject accumulated dust, preventing the bit from jamming deep inside the wall and overheating the carbide tip.
