The Simpson Strong-Tie MDPL03724 3/8 in. x 24 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, this bit delivers exceptional drilling speed, durability, and ease of use in demanding concrete and masonry applications. Built from a chromium-nickel-molybdenum steel alloy body and conforming to ANSI Standard B212.15, the MDPL03724 is purpose-built for professionals who require precision, long service life, and reliable performance on every job.

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
• 2-Cutter Head design optimized for fast, accurate penetration in concrete and masonry
• SDS-plus shank provides secure tool-free bit changes and efficient energy transfer from the rotary hammer

Frequently Asked Questions

What type of shank does the MDPL03724 use, and which rotary hammers is it compatible with?

The MDPL03724 features an SDS-plus shank, which is designed to fit SDS-plus rotary hammers. This shank style provides secure, tool-free bit insertion and efficient energy transfer during hammer drilling operations.

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

The MDPL03724 has an overall length of 24 in., while its usable drilling depth is 22 in. The difference accounts for the SDS-plus shank portion that is held within the rotary hammer chuck, which is not available for actual material penetration.

How does the bit design 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 helps improve drilling speed and keeps the bore clear during operation.

What makes the carbide inserts and steel body on this bit durable for heavy-duty use?

The carbide inserts are uniformly brazed to maximize bit life and consistency. The chromium-nickel-molybdenum steel alloy body is further enhanced through heat-treatment procedures and a shot-peened finish, which together increase surface hardness, reduce bit wear, improve resistance to bending forces, and extend overall service life.
