Simpson SDS-Plus Drill Bit 7/8 in. x 12-1/4 in. 2-Cutter Head Carbide-Tipped is a premium-quality, professional-grade rotary hammer bit from Simpson, purpose-built for demanding concrete and masonry drilling applications. Engineered to the highest industry standards and manufactured to meet precise tolerance requirements, this carbide-tipped bit pairs a 2-Cutter Head design with an SDS-plus shank to deliver consistent drilling speed, extended service life, and reliable performance job after job.

Key Features

• Uniformly brazed carbide inserts - provide consistent contact with the work surface, resulting in longer bit life and more holes drilled before replacement is needed
• Centering tip design - facilitates easy spot drilling so the bit stays on target from the first strike, reducing slippage and improving accuracy
• Chromium-nickel-molybdenum steel alloy body - delivers the toughness needed for hammering applications while supporting an extended service life under heavy use
• Heat-treatment procedures and shot-peened finish - increase surface hardness and drilling speed, reduce drill bit wear, and improve resistance to bending forces for reliable performance under load
• Chisel-shaped drill-bit head - penetrates the material efficiently and directs concrete dust into the multi-flute spiral, keeping the cutting zone clear
• High-volume, multi-flute spiral - quickly channels concrete dust from the hole to improve drilling speed and reduce clogging during deep drilling
• ANSI Standard B212.15 compliance - confirms the bit meets rigorous industry requirements, giving professionals confidence in its quality and dimensional consistency
• SDS-plus shank - allows quick, tool-free bit changes and full compatibility with SDS-plus rotary hammer drills, reducing downtime on the job

Why This Product

• Professional-grade construction built to last - the combination of uniformly brazed carbide inserts, a chromium-nickel-molybdenum alloy body, and a heat-treated, shot-peened finish means this bit is engineered to outlast standard drill bits in tough concrete and masonry conditions
• Faster drilling with less effort - the chisel-shaped 2-Cutter Head and high-volume multi-flute spiral work together to break material efficiently and evacuate dust continuously, keeping drilling speed high without forcing the operator to stop and clear debris
• Precision from start to finish - the centering tip helps lock the bit onto the target spot before drilling begins, and ANSI B212.15 compliance ensures diameter tolerances are held to industry-standard accuracy throughout the full 10 in. drilling depth
• Seamless compatibility with SDS-plus hammer drills - the SDS-plus shank fits a wide range of professional rotary hammer drills and enables tool-free bit swaps, making this a practical, ready-to-use choice for crews who need reliable performance without setup delays
