The Simpson SDS-Plus Drill Bit 1/4 in. x 16 in. 2-Cutter Carbide Tip is a professional-grade rotary hammer bit engineered for demanding concrete, masonry, and hard-material drilling applications. Built to precise tolerance requirements and conforming to ANSI Standard B212.15, this bit delivers the reliability and consistency that contractors and tradespeople require on the job site. With a 14 in. drilling depth and 16 in. overall length, it handles deep anchor and fastener holes with confidence, while the SDS-plus shank ensures quick, tool-free bit changes and a secure connection with compatible rotary hammer tools.

Key Features

• Uniformly brazed carbide inserts - consistent bonding across the cutting tip means the bit maintains its edge longer, reducing the frequency of replacements on extended jobs.
• Centering tip design - most bits in this line include a centering tip that makes it easier to start a hole accurately without walking, saving setup time and improving placement precision.
• Chromium-nickel-molybdenum steel alloy body - this high-strength alloy construction supports the repeated impact loads of rotary hammer use, delivering hammering quality and extended service life under heavy-duty conditions.
• Heat-treatment procedures and shot-peened finish - these proprietary processes increase surface hardness, improve drilling speed, reduce bit wear, and strengthen the bit's resistance to bending forces during use.
• Chisel-shaped 2-cutter drill-bit head - the head geometry penetrates material efficiently and simultaneously directs concrete dust into the flute system, keeping the cutting zone clear for faster progress.
• High-volume, multi-flute spiral - the flute design quickly channels concrete dust out of the hole as you drill, reducing clogging, improving drilling speed, and extending bit life.
• ANSI Standard B212.15 compliance - dimensional conformance to this industry standard means the bit fits and performs as expected in SDS-plus rotary hammers from a wide range of professional tool manufacturers.
• SDS-plus shank - the industry-standard shank interface provides positive chuck engagement and allows fast, tool-free bit swaps, keeping workflow moving without interruption.

Why This Product

• Professional-grade construction engineered for longevity - the combination of a chromium-nickel-molybdenum steel alloy body, uniformly brazed carbide inserts, and a shot-peened hardened finish means this bit is built to hold up through repeated use rather than wearing down after a handful of holes.
• Faster drilling with less effort - the chisel-shaped 2-cutter head and high-volume multi-flute spiral work together to penetrate material quickly and evacuate debris continuously, so the bit stays sharp and the hole stays clear without stopping to clean out dust.
• Precision and consistency on every hole - ANSI Standard B212.15 compliance and a centering tip design ensure accurate placement from the first contact, which matters when drilling for anchors, fasteners, or any application where hole location is critical.
• Broad compatibility with a reliable, standardized connection - the SDS-plus shank interfaces securely with SDS-plus rotary hammer tools across the industry, giving users a confident, rattle-free connection and effortless bit changes on the job.

Frequently Asked Questions

What type of rotary hammer is this drill bit compatible with?

This drill bit features an SDS-plus shank, which is the industry-standard connection type compatible with SDS-plus rotary hammer tools from a wide range of professional tool manufacturers. The SDS-plus interface provides a secure, tool-free bit change and positive chuck engagement during operation.

What is the maximum drilling depth this bit can achieve?

The Simpson MDPL02516 provides a maximum drilling depth of 14 in., with an overall bit length of 16 in. The additional length beyond the drilling depth accommodates the chuck engagement and allows for proper positioning of the tool during use.

What materials and processes give this bit its extended service life?

This bit is constructed with a chromium-nickel-molybdenum steel alloy body that ensures superior hammering quality and extended service life. Uniformly brazed carbide inserts provide consistent cutting performance, while heat-treatment procedures and a shot-peened finish increase surface hardness, reduce wear, and improve resistance to bending forces.

Does this drill bit meet any industry standards for quality and dimensional accuracy?

Yes. Simpson Strong-Tie MDPL02516 drill bits conform to ANSI Standard B212.15, ensuring they meet precise tolerance requirements for diameter and dimensional accuracy. This compliance guarantees consistent, reliable performance when used for anchoring and fastening applications that require exact hole sizing.
