The Simpson SDS-Plus Drill Bit 11/16 in. x 8 in. 2-Cutter Head Carbide-Tipped is a premium-quality, professional-grade rotary hammer bit from Simpson, engineered for precise, high-speed drilling in concrete and masonry. Manufactured to the highest industry standards and built to meet exact tolerance requirements, this SDS-plus shank bit incorporates proprietary design features that enhance durability, drilling speed, and ease of use across demanding construction and anchoring applications.

Key Features

• Uniformly brazed carbide inserts - stress is distributed evenly across the entire cutting edge, resulting in longer bit life and more consistent performance over extended use
• Centering tip - facilitates easy spot drilling so you can position holes accurately without the bit wandering at the start of a cut
• Chromium-nickel-molybdenum steel alloy body - ensures hammering quality and extended service life, standing up to the repeated impact forces of rotary hammer drilling
• Heat-treatment procedures and shot-peened finish - increase surface hardness, drilling speed, and resistance to bending forces while reducing drill bit wear over time
• ANSI Standard B212.15 compliance - confirms the bit meets recognized industry tolerances, giving professionals confidence in consistent hole diameter and quality
• Chisel-shaped drill-bit head - penetrates material efficiently and directs concrete dust into the multi-flute spiral, keeping the cutting zone clear for faster progress
• High-volume, multi-flute spiral - quickly channels concrete dust from the hole, improving drilling speed and reducing the need to withdraw the bit to clear debris

Why This Product

• Professional-grade construction built for the jobsite - the chromium-nickel-molybdenum alloy body combined with heat-treatment and a shot-peened finish delivers the durability and hammering quality that demanding concrete and masonry drilling requires, reducing downtime from premature bit failure
• Engineered for speed without sacrificing precision - the chisel-shaped head and high-volume multi-flute spiral work together to clear debris continuously, maintaining drilling speed while the centering tip keeps hole placement accurate from the first contact
• Uniformly brazed carbide tips mean fewer bit changes - consistent bonding across the carbide cutting inserts distributes wear evenly, so the bit holds its edge longer and stays productive through more holes before replacement is needed
• SDS-plus shank compatibility for tool-free convenience - the SDS-plus shank fits a wide range of rotary hammer drills, enabling quick bit swaps and efficient transfer of hammering energy so you spend less time setting up and more time drilling

Frequently Asked Questions

What type of shank does the Simpson MDPL06808 drill bit use?

The MDPL06808 features an SDS-plus Shank, which is compatible with SDS-plus rotary hammer drills. This shank design allows for quick, tool-free bit changes and efficient transfer of hammering energy during drilling.

What is the drilling depth and overall length of this bit?

The Simpson MDPL06808 has a drilling depth of 6 in. and an overall length of 8 in., with a diameter of 11/16 in. These dimensions make it well suited for anchoring and fastening applications that require precise, consistent hole depths in concrete and masonry.

What makes the carbide inserts on this drill bit last longer?

The carbide inserts are uniformly brazed onto the bit, which ensures a consistent and secure bond across the entire cutting edge. This uniform brazing process distributes stress evenly during drilling, resulting in longer bit life and more reliable performance over extended use.

How does the design of this bit help manage concrete dust during drilling?

The chisel-shaped drill-bit head penetrates the material and directs concrete dust into the multi-flute spiral. The high-volume, multi-flute spiral then quickly channels that concrete dust from the hole, which improves drilling speed and helps keep the hole clear for more accurate, efficient drilling.
