Simpson SDS-Plus Drill Bit 3/4 in. x 8 in. 2-Cutter Head Carbide-Tipped is a professional-grade rotary hammer bit from Simpson, engineered for demanding concrete, masonry, and demolition applications where precision hole placement and long service life are non-negotiable. Built on a chromium-nickel-molybdenum steel alloy body with uniformly brazed carbide inserts, this SDS-plus bit delivers fast, accurate drilling in tough base materials while standing up to the repetitive impact forces of rotary hammer use on the jobsite.

Key Features

• Uniformly brazed carbide inserts - consistent tip integrity across the full cutting edge means the bit stays sharp longer, reducing replacement frequency on high-volume drilling jobs
• Centering tip design - facilitates easy spot drilling so you can start holes accurately without walking, saving time on layout-critical anchor installations
• Chromium-nickel-molybdenum steel alloy body - engineered specifically for hammering quality and extended service life, so the shank and flute body resist cracking and fatigue under sustained impact
• Heat-treatment procedures and shot-peened finish - increase surface hardness, drilling speed, reduce drill bit wear, and improve resistance to bending forces, keeping the bit performing true even under lateral stress
• ANSI Standard B212.15 compliance - confirms the bit meets established dimensional and performance tolerances, ensuring reliable compatibility with standard SDS-plus rotary hammers and consistent hole sizing for anchor specifications
• Chisel-shaped 2-cutter drill-bit head - penetrates material aggressively and directs concrete dust into the multi-flute spiral, reducing clogging and maintaining cutting efficiency through the full drilling depth
• High-volume, multi-flute spiral - quickly channels concrete dust from the hole during drilling, improving drilling speed and reducing the need to withdraw the bit to clear debris

Why This Product

• Precision-manufactured to tight tolerances - the bit is produced to meet precise tolerance requirements, which means cleaner holes, better anchor seating, and fewer do-overs on critical fastening applications in concrete and masonry
• Purpose-built for professional rotary hammer use - the SDS-plus shank provides a secure, tool-free interface with SDS-plus rotohammers, and the chromium-nickel-molybdenum alloy body is specifically formulated to handle the hammering forces these tools generate without premature fatigue
• Engineered for faster drilling with less wear - the combination of a shot-peened finish, heat-treated body, and high-volume multi-flute spiral work together to increase drilling speed and reduce bit wear simultaneously, lowering cost-per-hole over the life of the tool
• Backed by Simpson Strong-Tie engineering standards - produced in Germany to the highest industry standards for Simpson, this carbide-tipped bit is part of a complete professional drilling system designed to support structural fastening and anchor installation workflows

Frequently Asked Questions

What type of shank does the MDPL07508 use, and which tools is it compatible with?

The MDPL07508 features an SDS-plus shank, which is the industry-standard interface designed to fit SDS-plus rotary hammers and rotohammers. This shank type provides a secure, tool-free bit change and allows the hammer mechanism to drive the bit efficiently during concrete drilling.

What are the key dimensions of this drill bit?

This drill bit has a diameter of 3/4 in., an overall length of 8 in., and a maximum drilling depth of 6 in., making it well-suited for medium-depth anchor hole drilling in concrete and masonry applications.

What construction features contribute to the durability and long life of this bit?

The bit's longevity comes from several engineered features: uniformly brazed carbide inserts for consistent tip integrity, a chromium-nickel-molybdenum steel alloy body for hammering strength, and heat-treatment procedures combined with a shot-peened finish that increase surface hardness and resistance to bending forces while reducing wear over time.

How does this bit handle concrete dust during drilling?

The chisel-shaped drill-bit head is designed to penetrate material efficiently while directing concrete dust into the high-volume, multi-flute spiral. This spiral then quickly channels the dust out of the hole, helping maintain drilling speed and preventing clogging during use.
