Diablo 5/16" x 4" x 6" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit delivers one of the fastest and longest-lasting drilling solutions available for concrete and masonry applications. Engineered by Diablo with a unique brazing and hardening process, this SDS Plus rotary hammer bit is built to punch through concrete and brick/block with precision, speed, and exceptional tip longevity - giving tradespeople and contractors a reliable tool for anchor installation and general concrete drilling tasks.

Key Features

• Diablo Dura-Carbide construction withstands impact and high-heat applications - dramatically extending service life versus standard hammer drill bits so you replace bits less often and stay productive on the job
• Peak Point Tip design enables aggressive starts - producing clean, fast holes that are ready for common-sized anchors without additional cleanup
• Optimized brazing and hardening process extends the life of the carbide tips and increases productivity - meaning each bit holds its edge longer under demanding rotary hammer use
• Optimized four-flute design removes dust faster, keeping the carbide tips cooler - delivering ultimate strength and durability through even extended drilling sessions in concrete or brick/block
• 2-cutter carbide-tipped head - provides reliable material engagement and consistent hole accuracy in concrete and masonry surfaces
• SDS Plus shank - locks securely into corded and cordless SDS-Plus rotary hammer drills for efficient energy transfer and reduced operator fatigue

Why This Product

• For contractors drilling concrete anchor holes, the Peak Point Tip design produces clean, accurate holes sized for common anchors - reducing the need for rework or secondary passes
• The Dura-Carbide formulation and optimized hardening process mean this bit outlasts standard hammer bits in high-impact, high-heat conditions - lowering cost per hole over the life of the bit
• The four-flute dust-removal design keeps the tip cooler during use, protecting carbide integrity and maintaining drilling speed even in extended concrete or brick applications
• Compatibility with both corded and cordless SDS-Plus rotary hammers makes this bit a versatile choice for job sites where power source flexibility matters
