The Simpson 1/2 in. x 24 in. SDS-Plus Drill Bit with 2-Cutter Head is a premium, professional-grade carbide-tipped rotary hammer bit engineered for demanding concrete and masonry drilling applications. Built to meet precise tolerance requirements, this hardened steel bit delivers consistent performance in deep-hole drilling tasks where accuracy, durability, and efficient dust evacuation are critical to getting the job done right.

Key Features

• Uniformly brazed carbide inserts - result in longer bit life and consistent cutting performance across extended use, reducing the need for frequent bit replacements on the job site.
• Centering tip - facilitates easy spot drilling for accurate hole placement, minimizing bit walk and improving precision from the first contact with the material.
• Chromium-nickel-molybdenum steel alloy body - ensures hammering quality and extended service life, standing up to the repeated impact forces generated by SDS-plus rotary hammer drills.
• Heat-treatment procedures and shot-peened finish - increase surface hardness and drilling speed, reduce drill bit wear, and improve resistance to bending forces, keeping the bit performing reliably under heavy use.
• Chisel-shaped 2-cutter drill-bit head - penetrates concrete and masonry efficiently and directs concrete dust into the multi-flute spiral, keeping the hole clear and maintaining cutting speed.
• High-volume, multi-flute spiral - quickly channels concrete dust from the hole to improve drilling speed and prevent clogging during deep-hole drilling passes.
• ANSI Standard B212.15 compliance - confirms the bit meets verified dimensional accuracy and quality standards, giving contractors confidence in consistent fit and performance with compatible tooling.
• SDS-plus shank design - enables secure, tool-free bit changes and ensures compatibility with SDS-plus rotary hammer drills, streamlining workflow on busy job sites.

Why This Product

• Professional-grade construction built for deep-hole work - with a 22 in. drilling depth capacity and a hardened chromium-nickel-molybdenum steel alloy body, this bit is purpose-built for contractor-level concrete drilling tasks that standard bits cannot handle.
• Faster drilling with less downtime - the combination of a chisel-shaped 2-cutter head, high-volume multi-flute spiral, and shot-peened finish work together to maximize drilling speed and reduce wear, so crews spend less time changing bits and more time working.
• Precision from start to finish - the integrated centering tip allows accurate spot drilling before full engagement, reducing layout errors and rework when hole placement matters most in concrete anchor and masonry fastener installations.
• Verified quality backed by Simpson - manufactured to ANSI Standard B212.15 and produced to the highest industry standards by Simpson Strong-Tie, this rotary hammer bit offers professionals a reliable, spec-compliant tool they can depend on across demanding drilling and demolition applications.

Frequently Asked Questions

What type of drill is required to use this bit?

This bit features an SDS-plus shank, which means it is compatible with SDS-plus rotary hammer drills. The SDS-plus shank allows for secure, tool-free bit changes and is designed for efficient hammer drilling performance.

What are the key dimensions of this drill bit?

This drill bit has a 1/2 in. diameter, an overall length of 24 in., and a maximum drilling depth of 22 in.

What materials is this drill bit designed to drill into?

This drill bit is designed for drilling into concrete and masonry. The chisel-shaped 2-cutter head penetrates the material efficiently and directs concrete dust into the high-volume multi-flute spiral, which quickly channels dust out of the hole to improve drilling speed and reduce clogging.

What quality standards does this drill bit meet, and what makes it durable?

This drill bit conforms to ANSI Standard B212.15 for dimensional accuracy and quality assurance. Durability is achieved through uniformly brazed carbide inserts, a chromium-nickel-molybdenum steel alloy body, and heat-treatment procedures combined with a shot-peened finish that increase surface hardness, reduce wear, and improve resistance to bending forces.
