The Simpson 5/32 in. x 4-1/4 in. SDS-Plus Carbide 2-Cutter Head Drill Bit is a premium, professional-grade masonry drill bit engineered for demanding concrete drilling applications where precision, durability, and consistent performance are non-negotiable. Built on a chromium-nickel-molybdenum steel alloy body and tipped with uniformly brazed carbide inserts, this bit is designed to meet the exacting tolerance requirements that professional contractors depend on. Its SDS-Plus shank design pairs with standard rotary hammers for efficient, high-impact drilling, while proprietary engineering details work together to extend service life and accelerate drilling speed on tough substrates.

Key Features

• Uniformly brazed carbide inserts - consistent bonding strength across the entire tip means the cutting edge holds up longer under repeated impact, reducing replacement frequency and downtime on the job.
• Chromium-nickel-molybdenum steel alloy body - this high-grade alloy is specifically chosen to absorb hammering forces and resist fatigue, giving the bit an extended service life compared to standard steel bodies.
• Heat-treatment procedures and shot-peened finish - increase surface hardness and resistance to bending forces, while simultaneously improving drilling speed and reducing bit wear during heavy use.
• Chisel-shaped 2-Cutter Head tip - penetrates concrete and masonry material efficiently while directing concrete dust into the multi-flute spiral, keeping the cutting zone clear for faster, cleaner holes.
• High-volume, multi-flute spiral - quickly channels concrete dust out of the hole as you drill, reducing clogging and heat buildup so the bit maintains speed and accuracy throughout each pass.
• Conforms to ANSI Standard B212.15 - compliance with this established industry standard ensures the bit meets verified dimensional and performance requirements, giving professionals confidence in predictable, repeatable results.
• SDS-Plus shank compatibility - designed for use with SDS-Plus rotary hammers, enabling secure bit retention under high-impact drilling conditions without sacrificing the ease of tool-free bit changes.

Why This Product

• Professional-grade materials engineered to last - the combination of uniformly brazed carbide inserts and a chromium-nickel-molybdenum alloy body means this rotary hammer bit is built to withstand the repeated impact and friction of concrete drilling far better than commodity alternatives.
• Faster drilling through smarter dust management - the chisel-shaped head and high-volume multi-flute spiral work as a system, directing debris out of the hole continuously so the bit cuts faster and runs cooler, reducing wear over the life of the tool.
• Verified performance you can spec with confidence - ANSI Standard B212.15 compliance means this carbide-tipped masonry bit has been held to established dimensional and performance benchmarks, making it a reliable choice for installations where tolerances matter.
• A trusted name in structural fastening and drilling - Simpson is a recognized brand among building professionals, and this drill bit is part of a complete line developed and manufactured to the same high standards applied across their full range of anchoring and fastening products.
