The Diablo Rebar Demon™ series delivers unmatched durability, speed, and precision for drilling into reinforced concrete. Designed with a 4-cutter full-carbide head, these SDS-Plus and SDS-Max bits handle the toughest applications, including rebar, with controlled carbide wear, reduced vibration, and exceptional longevity. Built with up to 2X more Dura-Carbide™, they resist heat up to 1800°F—far beyond standard bits that fail at 800°F. Tri-Metal Fusion Welding reinforces the carbide head for extreme impact resistance, while the precision tip ensures stable, accurate holes for anchor setting. Optimized flutes remove dust efficiently, keeping the bit cooler and maintaining peak performance in both corded and cordless rotary hammers.
