When concrete won’t back down, you need drilling power you can trust. The Diablo DMAPL2240-P25 3/8" x 10" x 12" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bits (25-pk) are engineered to fuel fast, precise holes in tough masonry with lasting performance. Built around a meticulous brazing and hardening process, the carbide tips stay sharper longer, so you spend less time changing bits and more time getting the job done.

• Two-cutters with carbide tips deliver efficient material removal and a durable bite in concrete, reducing wandering and delivering consistently accurate holes.
• Peak Point tip design enables aggressive starts for clean, fast holes at common anchor sizes, minimizing rework and pilot drilling.
• SDS-Plus compatibility optimized for both corded and cordless rotary hammers, ensuring reliable performance across job sites and tool setups.
• Long-lasting performance thanks to a robust brazing and hardening process that resists wear through multiple concrete driller sessions—great for repeated anchors and heavy-duty projects.
• 25-piece pack provides a ready-to-work supply, reducing downtime and keeping you prepared for a variety of concrete drilling tasks.

Perfect for professionals and serious DIYers tackling anchor installations, electrical and plumbing runs, or straight-hole work in concrete walls and floors. The DMAPL2240-P25 is designed to deliver consistent results across a range of substrates—from solid concrete to dense masonry—so you can trust each hole to hold securely.

• Anchor installation in concrete and block walls
• Drilling for conduit and wiring passes in slabs and columns
• Fast, reliable holes for masonry anchors in brickwork and mortar joints

Pro tips for best results: start with a steady, controlled feed and minimal axial pressure to let the bit bite cleanly; use the hammer function with appropriate impact settings, then pause periodically to clear dust and cool the tip; keep the drill perpendicular to the surface for perfectly straight holes; and maintain a moderate drilling pace to maximize bit life and hole quality.
