Description

Achieve Professional Precision and 2X Faster Drilling Speeds in Toughest Masonry

The Bosch HCBG18T 1/2" x 12" BlueGranite Turbo™ Carbide Hammer Drill Bit is engineered for professionals who demand maximum efficiency on the job site. Designed to deliver 5x longer life and 2x faster speeds than standard masonry bits, this bit significantly reduces downtime and increases on-the-job productivity. Whether you are anchoring into aged concrete, drilling through hard brick, or working with stone and block, the upgraded four-grind head provides additional cutting angles that shear through material with ease. The multi-grind centering tip ensures that your holes start exactly where you want them, eliminating bit walking and ensuring surgical precision in every application.

Redesigned to meet the demands of modern high-torque equipment, this impact-rated bit features a hex shank that provides an aggressive hold in both impact drivers and hammer drill/drivers. The bit is further enhanced with milled U-flutes featuring deep-cut spirals for rapid dust removal, keeping the hole clean and preventing heat buildup that can compromise bit integrity. Manufactured with Bosch-made carbide, this bit offers outstanding durability under heavy loads and is specifically optimized for high-impact percussion applications.

Pro-Tip: When drilling deep holes in masonry, use a "pecking" motion by periodically pulling the bit slightly out of the hole while it is still spinning. This allows the deep-cut U-flutes to eject packed dust more effectively, keeping the carbide tip cool and extending the life of your bit significantly during intensive 12-inch drilling runs.
