Introducing the Diablo DMAPLCC1040 1-9/16" SDS-Plus Carbide Tipped Thin Wall Core Bit — a purpose-built solution for professional concrete coring that blends speed, durability, and precision.

Designed for serious concrete work, the Diablo SDS-Plus Thin Wall Core Bit line delivers one of the fastest, longest-lasting coring experiences on the market. A unique brazing and hardening process bonds a carbide tip to a rugged thin-wall body, boosting both life and cutting efficiency so you can drill fast and produce clean, true holes from start to finish.

• Fast, clean cores: The thin-wall geometry reduces friction and helps chip evacuation, enabling quicker penetration and tighter hole tolerances.
• Durable carbide tips: Advanced brazing and hardening extend tip life, maintaining sharp cutting action through more holes per bit.
• Two ejector holes: Built-in ejectors simplify core removal when you’re finished, especially in deep or thick concrete sections.
• Optimized for SDS-Plus hammers: Delivers peak performance in both corded and cordless SDS-Plus rotary hammers, ensuring consistent results across tools.
• 1-9/16" bore capacity: Ideal for anchor installations, conduit passes, and other through-holes in concrete and masonry projects.

This core bit is perfect for professionals who install anchors, run wiring or plumbing, or mount heavy fixtures in concrete structures where speed and precision matter. The combination of carbide-tipped cutting edges, thin-wall construction, and practical ejector holes translates to more holes per bit, reduced downtime, and higher overall productivity on demanding jobs.

Why choose this over standard bits? The thin-wall design minimizes binding and enhances chip clearance, while the carbide tips resist wear far longer than conventional steel tips. You’ll experience faster hole creation and longer bit life, making it a dependable choice for repeated core drilling across multiple sites.

Tips for best results: pair this bit with a capable SDS-Plus hammer (cordless or corded), maintain a steady RPM, and apply measured feed pressure to maximize cut life and hole quality. Keep the bit perpendicular to the surface for true cores, and allow the hammer to work steadily rather than forcing the bit through tough sections.
