The Simpson Strong-Tie MDPL03112 5/16 in. x 12 in. SDS-plus Shank Drill Bit is a premium-quality, professional-grade carbide-tipped drill bit engineered to the highest industry standards. Featuring a 2-cutter head design and SDS-plus shank compatibility, this bit is built for demanding concrete and masonry drilling applications where durability, speed, and precision are essential. A chromium-nickel-molybdenum steel alloy body combined with uniformly brazed carbide inserts delivers exceptional longevity and consistent performance even under heavy hammering conditions.

Key Features

• Uniformly brazed carbide inserts result in longer bit life
• Chromium-nickel-molybdenum steel alloy body ensures hammering quality and extended service life
• Heat-treatment procedures and shot-peened finish increase surface hardness, drilling speed, reduces drill bit wear and improves resistance to bending forces
• Drill bits conform to ANSI Standard B212.15
• Chisel-shaped drill-bit head penetrates the material and directs concrete dust into the multi-flute spiral
• High-volume, multi-flute spiral quickly channels concrete dust from the hole to improve drilling speed
• 2-cutter head configuration for efficient material penetration
• SDS-plus shank for secure, tool-free bit changes in compatible rotary hammers
• Professional-grade construction manufactured to precise tolerance requirements

Frequently Asked Questions

What type of shank does the MDPL03112 drill bit use?

The MDPL03112 features an SDS-plus shank, which allows for secure, tool-free bit changes and is compatible with SDS-plus rotary hammer drills.

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

This drill bit has a drilling depth of 10 in. and an overall length of 12 in., providing ample reach for deeper anchor and fastener installations in concrete and masonry.

What makes the carbide tip on this bit last longer than standard bits?

The carbide inserts are uniformly brazed onto the bit, ensuring a consistent and secure bond that resists premature wear. Combined with the heat-treatment procedures and shot-peened finish, the bit achieves increased surface hardness and improved resistance to bending forces, all of which contribute to extended service life.

How does the bit manage concrete dust during drilling?

The chisel-shaped drill-bit head is designed to penetrate material while directing concrete dust into the high-volume, multi-flute spiral. The spiral then quickly channels that dust out of the hole, improving drilling speed and reducing clogging during operation.
