Bosch HCBG27T Blue Granite Hammer Drill Bit 1x10x12 3 Pack

Product Description

The ROBERT BOSCH TOOL GROUP HCBG27T is a Blue Granite hammer drill bit engineered for masonry, brick, and concrete applications. Measuring 1 inch in diameter with a 10-inch working length and 12-inch overall length, this bit is built for professional tradespeople who need consistent, fast performance in rotary hammer and hammer drill applications. The 4-grind head delivers two times more cutting angles compared to standard configurations, extending bit life while increasing penetration speed. A multi-grind carbide centering tip ensures accurate starts in brick, block, and masonry surfaces without walking or skipping. Milled U-flutes with deep-cut spirals provide rapid dust evacuation to keep the cutting zone clear during extended use.

This bit is suited for residential and commercial masonry work including anchor setting, conduit penetrations, and structural fastening in brick and block walls. The robust bit head construction is optimized for impact applications, making it compatible with standard hammer drills and rotary hammers commonly used by electricians, plumbers, HVAC installers, and general contractors. The package includes 3 bits per unit, providing a ready supply for high-volume drilling tasks on job sites where bit wear is expected. Its design targets professionals who require reliable, repeatable performance when drilling into hard masonry substrates.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer and hammer drill operation.

Wear appropriate eye protection and a dust mask when drilling into masonry, as silica-containing dust is generated. Follow applicable OSHA and job site safety guidelines for concrete and masonry drilling operations.
