Description

Master the Toughest Masonry with Diablo’s SPEEDemon Red Granite Carbide-Tipped Hammer Drill Bits

The Diablo DMARG1100 5/16" x 6" SPEEDemon™ Red Granite PLUS™ hammer drill bit is engineered to be the fastest and most durable solution for drilling into concrete, stone, and masonry. Featuring an impact-resistant carbide tip optimized through a unique brazing and hardening process, this bit withstands extreme heat and delivers up to 4X longer life than standard masonry bits. Whether you are anchoring into structural concrete or performing precision work in marble and granite, the specialized Grip Point Tip PLUS™ design ensures aggressive, stable starts for clean and accurate holes every time.

Engineered for maximum jobsite efficiency, this bit features the Impact Strong™ hex shank, which increases stability and durability in both cordless and corded impact drivers and hammer drills. The optimized "U-flute" design rapidly removes dust from the hole, keeping the carbide tip cooler and extending the overall life of the tool. Specifically designed to deliver more holes per charge in cordless applications, the DMARG1100 provides the ultimate combination of speed, strength, and impact resistance for professional-grade results in brick, block, and natural stone.

Pro-Tip: When drilling into hard stone like granite or marble, start the hole at a lower speed to allow the Grip Point Tip to seat firmly. Once the hole is established, increase the speed but avoid excessive downward pressure; let the carbide tip and hammer action do the work to prevent overheating and ensure the cleanest finish.
