The Simpson 7/8 in. x 8 in. SDS-Plus Carbide 2-Cutter Head Drill Bit is a professional-grade rotary hammer bit engineered for precise, high-performance drilling in concrete and masonry. Built on a chromium-nickel-molybdenum steel alloy body and tipped with uniformly brazed carbide inserts, this bit is designed to meet demanding drilling and demolition requirements on job sites where consistent hole tolerances and long service life are non-negotiable. The 2-cutter head configuration, chisel-shaped tip, and high-volume multi-flute spiral work together to deliver fast, clean penetration with efficient dust removal - making it a reliable choice for anchor installation, mechanical fastener work, and structural concrete drilling.

Key Features

• Uniformly Brazed Carbide Inserts - Consistent bonding along the cutting edge maintains sharpness through heavy use, resulting in longer bit life and fewer bit changes on the job.
• Centering Tip Design - A built-in centering tip on most bits helps the bit self-locate on hard surfaces, reducing walking and improving drilling accuracy from the first contact.
• Chromium-Nickel-Molybdenum Steel Alloy Body - This premium alloy composition handles the repeated impact forces of rotary hammer use, ensuring hammering quality and extended service life in demanding applications.
• Heat-Treatment and Shot-Peened Finish - Specialized surface treatment increases hardness, boosts drilling speed, reduces wear, and improves resistance to bending forces so the bit holds up under sustained heavy-duty use.
• ANSI Standard B212.15 Compliance - Dimensional conformance to this industry standard ensures the bit works accurately with SDS-plus rotary hammers and meets tolerance requirements for anchor and fastener hole installations.
• Chisel-Shaped 2-Cutter Head - The head geometry penetrates material efficiently and directs concrete dust directly into the flute spiral, keeping the cutting zone clear and maintaining drilling speed.
• High-Volume Multi-Flute Spiral - Rapidly channels concrete dust and debris out of the hole during drilling, reducing friction buildup and helping sustain consistent penetration rates through the full depth of the cut.

Why This Product

• Professional Quality Built to Exacting Standards - Simpson engineered this bit to precise tolerance requirements with proprietary features that enhance durability and drilling speed, making it a dependable tool for structural anchor work and professional concrete drilling where accuracy matters.
• Longer Service Life Through Superior Material Science - The combination of a chromium-nickel-molybdenum alloy body, uniformly brazed carbide inserts, and a heat-treated shot-peened finish means this bit resists wear, bending, and premature dulling - reducing downtime and replacement costs over the course of a project.
• Faster Drilling With Built-In Dust Management - The chisel-shaped 2-cutter head and high-volume multi-flute spiral are designed to work together, clearing debris from the hole continuously so drilling speed stays consistent from start to finish rather than slowing as dust accumulates.
• Designed Specifically for SDS-Plus Rotary Hammers - The SDS-plus shank provides secure, tool-free bit changes and efficient transfer of hammer energy, making this bit a straightforward drop-in choice for contractors already working with SDS-plus equipment on masonry and concrete applications.
