The Simpson SDS-Plus Drill Bit 9/16 in. x 6-1/4 in. 2-Cutter Carbide Tip is a professional-grade rotary hammer bit engineered by Simpson to deliver precise, high-speed drilling in concrete and masonry applications. Built to meet strict tolerance requirements, this carbide-tipped bit combines a hardened alloy steel body with proprietary design features that maximize durability, drilling efficiency, and ease of use on demanding job sites.

Key Features

• Uniformly brazed carbide inserts - consistent bonding across the tip means the cutting edge holds up longer under repeated impact, reducing the need for frequent bit replacement
• Centering tip design - facilitates easy spot drilling so the bit stays on target from the first strike, saving time and preventing surface damage
• Chromium-nickel-molybdenum steel alloy body - this high-grade alloy composition ensures the body can absorb hammering forces without fatigue, extending overall service life even in heavy-use conditions
• Heat-treatment procedures and shot-peened finish - increase surface hardness, improve drilling speed, reduce drill bit wear, and strengthen resistance to bending forces so the bit performs reliably under stress
• Chisel-shaped 2-Cutter drill-bit head - penetrates 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 during drilling, maintaining speed and reducing clogging on deep passes
• SDS-plus shank - provides secure, tool-free chuck engagement compatible with SDS-plus rotary hammers, ensuring optimal energy transfer from the hammer mechanism to the bit
• Conforms to ANSI Standard B212.15 - compliance with this industry standard confirms dimensional accuracy and consistent quality, giving professionals confidence in predictable performance

Why This Product

• Built for professional reliability - the combination of a chromium-nickel-molybdenum alloy body, uniformly brazed carbide inserts, and a heat-treated, shot-peened finish creates a drill bit designed to withstand the rigors of repeated rotary hammer use without premature wear or failure
• Engineered for faster, cleaner drilling - the chisel-shaped 2-Cutter head and high-volume multi-flute spiral work together to break material efficiently and evacuate concrete dust continuously, so drilling speed stays high and hole quality stays consistent throughout each pass
• Precise fit and verified quality - manufactured to ANSI Standard B212.15 tolerances, this bit is dimensionally consistent and compatible with standard SDS-plus rotary hammers, making it a dependable choice for anchoring, fastening, and concrete work where accuracy matters
• Designed to reduce downtime - the centering tip, durable carbide tip bonding, and wear-resistant surface treatment all contribute to a bit that starts on target, lasts longer between replacements, and keeps work moving without unnecessary interruptions

Frequently Asked Questions

What type of shank does the MDPL05606 drill bit use?

The MDPL05606 features an SDS-plus shank, which is compatible with SDS-plus rotary hammers and provides a secure, tool-free bit engagement for efficient energy transfer during hammering and drilling.

What is the maximum drilling depth this bit can achieve?

The MDPL05606 has a drilling depth of 4 in., with an overall length of 6-1/4 in. and a diameter of 9/16 in.

What makes the carbide tip on this drill bit durable?

The carbide inserts are uniformly brazed to the bit, which ensures consistent bonding and longer bit life. The chromium-nickel-molybdenum steel alloy body, combined with heat-treatment procedures and a shot-peened finish, further increases surface hardness and resistance to bending forces.

How does this drill bit manage concrete dust during drilling?

The chisel-shaped drill-bit head penetrates the material and directs concrete dust into the high-volume, multi-flute spiral, which quickly channels that dust out of the hole. This design improves drilling speed and keeps the hole clean during operation.
