The Diablo SPEEDemon DMARG1130 is a carbide-tipped hammer drill bit engineered for fast, efficient drilling in concrete, masonry, and stone. This percussion-style bit combines a proprietary red granite carbide tip with advanced brazing and hardening technology to deliver extended bit life and sustained productivity. Whether you're working with cordless or corded impact and drill drivers, this bit minimizes downtime by staying sharp longer while maintaining accuracy even under heavy impact conditions.
The multi-ground Grip Point tip design enables aggressive starts that cut cleanly and quickly, producing fast, accurate holes. The reinforced shank reduces wobble and delivers the stability needed for precise holes in demanding applications. The U-Flute chip evacuation system rapidly clears debris, protecting the carbide tip from overheating and buildup.
Features and Benefits
