Description

Maximize Jobsite Productivity with High-Speed Masonry Bits

Equip your crew with the Bosch BlueGranite Turbo™ 3/16 in. Carbide Hammer Drill Bit 25-Pack (HCBG04B25T). Designed for professionals who demand efficiency and longevity, these bits deliver up to 5x longer life and 2x faster drilling speeds compared to standard masonry bits. The secret lies in the upgraded four-grind head and robust Bosch-made carbide tip, which create additional cutting angles for aggressive material removal. Whether you are drilling pilot holes for anchors in concrete, block, or brick, the multi-grind centering tip ensures precise, walk-free starts every time.

Engineered for versatility, these bits feature an impact-rated hex shank, allowing them to be used in today’s high-torque impact drivers as well as standard hammer drills. This eliminates the need to switch tools for pilot holes, streamlining your workflow. The milled U-flutes with deep-cut spirals efficiently evacuate dust to prevent overheating and binding, ensuring reliable performance hole after hole. This bulk 25-pack is the smart choice for contractors looking to reduce downtime and keep their projects moving forward.

Pro-Tip: The 3/16-inch diameter bit is the standard size required for installing 1/4-inch concrete screws (like Tapcon®). When drilling multiple holes for long runs of shelving or conduit, carry a spare bit in your pocket—even the toughest carbide eventually wears down when hitting hidden aggregate.
