The ROBERT BOSCH TOOL GROUP HCBG06T BluGranite Turbo Carbide Hammer Drill Bit is a heavy-duty masonry bit engineered for demanding concrete, brick, and general masonry work. Sold in a 5-pack, each bit measures 0.25 inches in diameter, 4 inches of flute length, and 6 inches overall length. The HCBG06T features a multi-grind carbide centering tip, a 4-grind head geometry, and milled U-flutes with deep-cut spirals. Bosch-made carbide construction is rated to deliver 5 times the service life and 2 times the drilling speed compared to standard masonry bits. Licensed HVAC, plumbing, and general trade professionals will find this bit suited for penetrating masonry assemblies during rough-in and retrofit work.
The HCBG06T is designed for use in hammer drills, hammer drill/drivers, and impact drivers thanks to its hex shank impact-rated design. The 0.25-inch hex shank seats directly into standard impact driver chucks, making it a versatile addition to a working tool bag. The 4-inch usable length provides adequate depth for typical masonry anchor and sleeve anchor installations in residential and light commercial settings. The robust bit head is built to hold up under repetitive impact loading in tough aggregate materials.
Designed for use in standard hex-chuck impact drivers and keyed or keyless chuck hammer drills and hammer drill/drivers that accept a 0.25-inch hex shank bit. Suitable for drilling into brick, concrete block, poured concrete, and general masonry substrates.
Installation should be performed by a qualified tradesperson familiar with hammer drill operation and applicable building codes. Before drilling into any wall, ceiling, or floor assembly, verify the absence of concealed electrical conduit, plumbing lines, and structural elements. Wear appropriate eye and respiratory protection when drilling masonry, as silica-containing dust is generated. Follow OSHA silica exposure guidelines and applicable local codes when working in enclosed spaces.
