Simpson MDPL07508 3/4 in. x 8 in. SDS-plus Shank Drill Bit is a professional-grade, carbide-tipped SDS-plus drill bit from Simpson Strong-Tie, engineered to deliver superior performance in concrete drilling and demolition applications. Built to the highest industry standards, this bit features a chromium-nickel-molybdenum steel alloy body and uniformly brazed carbide inserts that combine long service life with fast, precise drilling in demanding jobsite conditions.

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, drilling speed, and ease of use

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.
