Bosch HCBG23T Blugranite Turbo Carbide Hammer Drill Bit

Product Description

The ROBERT BOSCH TOOL GROUP HCBG23T is a carbide hammer drill bit from the BluGranite Turbo line, designed for drilling into brick, block, concrete, and masonry. The bit measures 3/4 inches in diameter with a 12-inch overall length, a 10-inch flute length, and a 10-inch usable length. The 0.375-inch hex shank is impact-rated, allowing use in both hammer drill/drivers and impact drivers. A four-grind head geometry and multi-grind carbide centering tip are built into the design to deliver faster starts and extended service life under heavy-load conditions. Licensed tradespeople and experienced masonry contractors are the primary installers for this bit.

The HCBG23T is suited for residential and commercial masonry applications where speed and bit longevity are priorities. The milled U-flutes with deep-cut spirals clear dust rapidly during drilling, keeping the cutting edge cooler and reducing bit wear. The hex shank design expands tool compatibility, making this bit a practical choice for crews running impact drivers alongside dedicated hammer drills. It is appropriate for anchor setting, conduit penetrations, and through-hole drilling in brick or concrete block.

Installation Notes

This bit is installed and used by masonry contractors, electricians, plumbers, and HVAC technicians requiring penetrations through masonry or concrete. Confirm that the tool chuck accepts a 0.375-inch hex shank before use. Always wear appropriate eye protection and a dust respirator when drilling masonry, in accordance with applicable OSHA and site safety requirements. Inspect the carbide tip and flutes for wear or damage before each use and replace the bit if the centering tip is chipped or the flutes are packed.
