Meet the Diablo DMAPL2420 SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit—crafted for serious concrete work. With a 5/8" diameter and a dual-cut design, this bit is built to deliver fast, accurate holes in tough masonry when you’re assembling anchors, fasteners, or structural components.

What sets this bit apart is the combination of a rugged carbide tip and a precision brazing/hardening process. The carbide tips resist wear from hard aggregates and rebar, extending service life and maintaining edge sharpness through repeated use. The result is fewer re-drills, less downtime, and more productive cuts per job site.

Key features and benefits

• Carbide-tipped durability informed by a proprietary brazing and hardening process that enhances wear resistance and longevity in concrete, masonry, and reinforced settings.
• Peak Point tip design enables an aggressive, straight start, reducing wandering and producing clean, precise holes for common anchor sizes.
• SDS-Plus 2-Cutter geometry provides efficient material removal with less friction, helping you drill faster without compromising hole quality.
• Corded or cordless compatibility optimized for performance in both types of SDS-Plus rotary hammers, ensuring reliable results across tools you already own.
• Long-length versatility 5/8" diameter with a 16" flute length and 18" overall length supports deep anchor installations and challenging drilling depths.

Ideal use cases

Designed for professionals who routinely drill into concrete, brick, and block for anchors, sleeve anchors, and other masonry fasteners. Whether you’re setting conduit supports, mounting heavy equipment, or anchoring structural elements, this bit maintains straightness and efficiency from start to finish.

Who benefits most

• Electricians, plumbers, and HVAC installers working in concrete cores and dense masonry.
• Masonry contractors performing anchor installations in reinforced concrete.
• Facility maintenance crews needing reliable, long-lasting drill bits for frequent use.

Tips for best results

• Use a pilot hole when working in particularly dense concrete to reduce stress on the bit and tool.
• Maintain steady, perpendicular alignment to the work surface to maximize hole accuracy and minimize bit wear.
• Let the hammer do the work—avoid excessive pressure that can cause bit chipping or bit walk.
• Pair with compatible SDS-Plus hammers for consistent performance and extend tool life by following manufacturer guidelines for speed and percussion settings.

For contractors and DIYers who demand dependable concrete drilling performance, the Diablo DMAPL2420 delivers a practical blend of speed, precision, and longevity. It’s the right choice when you need clean holes, steady starts, and a bit that stands up to repeated use in demanding masonry environments.
