The Simpson MDPL04306 7/16 in. x 6-1/4 in. SDS-plus Shank Drill Bit is a premium, professional-grade carbide-tipped drill bit from Simpson Strong-Tie, engineered to the highest industry standards for demanding concrete and masonry drilling applications. Featuring a 2-cutter head design and SDS-plus shank compatibility, this bit is built to deliver exceptional durability, precise hole placement, and fast, efficient material removal on professional job sites.

Key Features

• Uniformly brazed carbide inserts result in longer bit life
• Most bits contain a centering tip that facilitates easy spot drilling
• 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
• Designed to meet precise tolerance requirements with proprietary features that enhance durability and ease of use

Frequently Asked Questions

What type of shank does the Simpson MDPL04306 drill bit use?

The MDPL04306 features an SDS-plus shank, making it compatible with SDS-plus rotary hammer drills for efficient concrete and masonry drilling.

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

This drill bit has a maximum drilling depth of 4 in. and an overall length of 6-1/4 in., with a diameter of 7/16 in.

What makes the carbide inserts on this bit more durable?

The carbide inserts are uniformly brazed onto the bit, which ensures consistent bonding across the cutting edge and results in longer bit life compared to less precisely manufactured alternatives.

How does the body construction of this drill bit contribute to its performance?

The body is made from a chromium-nickel-molybdenum steel alloy, which is then subjected to heat-treatment procedures and a shot-peened finish. This process increases surface hardness, improves drilling speed, reduces wear, and enhances resistance to bending forces during heavy-duty hammering applications.
