Bosch HCBG14T Blugranite Turbo Hammer Drill Bit 3/8in 5-pack

Product Description

The ROBERT BOSCH TOOL GROUP HCBG14T is a BluGranite Turbo carbide hammer drill bit engineered for high-demand masonry drilling applications. Measuring 3/8 inches in diameter with a 12-inch overall length and a 10-inch flute length, this bit is built to outlast standard masonry bits significantly. The hex shank design is impact-rated at 0.3125 inches, allowing use in both impact drivers and hammer drill/drivers. The 4-grind head geometry provides two additional cutting angles compared to conventional bits, contributing to faster penetration rates and extended service life. Bosch-manufactured carbide is used throughout the cutting end, delivering consistent performance under heavy load conditions. Sold in a 5-pack unit quantity.

This bit is suited for residential and light commercial masonry work, including drilling into brick, concrete block, mortar, and similar masonry substrates. The multi-grind carbide centering tip enables accurate hole starts without walking, which is particularly useful when precision placement matters on a job site. Milled U-flutes with deep-cut spirals promote rapid dust evacuation during drilling, reducing heat buildup and keeping the bit cutting efficiently. Licensed HVAC technicians, plumbers, electricians, and general construction trades commonly reach for this bit when anchoring equipment, running conduit, or mounting hardware in masonry walls.

Installation Notes

This bit is installed by contractors and trade professionals familiar with rotary hammer or impact driver operation on masonry substrates. Always wear appropriate eye and respiratory protection when drilling into masonry, as fine silica dust is generated. Confirm the drilling mode setting on the tool matches the application before starting. Inspect the bit for carbide tip damage before each use and replace if the cutting edge is chipped or worn.
