The Simpson 3/8 in. x 18 in. SDS-Plus Carbide 2-Cutter Head Drill Bit is a professional-grade rotary hammer bit engineered for demanding concrete and masonry drilling applications. Built to precise tolerance requirements, this carbide-tipped bit delivers reliable, high-speed performance whether you are anchoring into concrete walls, drilling through block, or completing deep-bore tasks that require a clean, accurate hole at depth.

Key Features

• Uniformly brazed carbide inserts - bond the carbide tips securely to the bit body, reducing premature tip loss and extending overall bit life on tough materials
• Chromium-nickel-molybdenum steel alloy body - provides the hammering strength and resilience needed to withstand repeated impact cycles, keeping the bit performing reliably through extended service life
• Heat-treatment procedures and shot-peened finish - increase surface hardness, boost drilling speed, reduce drill bit wear, and improve resistance to bending forces so the bit holds up under heavy rotary hammer use
• Chisel-shaped drill-bit head - penetrates concrete and masonry efficiently while directing concrete dust into the multi-flute spiral, keeping the cutting zone clear for faster progress
• High-volume, multi-flute spiral - quickly channels concrete dust out of the hole, reducing clogging and improving drilling speed so you spend less time clearing debris
• 2-cutter head design - delivers efficient material penetration, making it well suited for anchor installation and other precision drilling tasks in concrete and masonry
• SDS-plus shank - fits any standard SDS-plus rotary hammer drill for a secure, tool-free bit change and consistent torque transfer during high-impact drilling
• Conforms to ANSI Standard B212.15 - ensures the bit meets established dimensional and performance standards, giving professionals confidence in hole accuracy and fit for anchor systems

Why This Product

• Professional-grade construction from start to finish - the combination of a chromium-nickel-molybdenum alloy body, uniformly brazed carbide inserts, and a heat-treated, shot-peened finish means this bit is built to handle the repetitive impact and friction of commercial and construction-site drilling without breaking down prematurely
• Engineered for deep, clean holes - with a 16 in. drilling depth and an 18 in. overall length, this bit reaches depths that shorter bits simply cannot, making it the right tool for deep anchor installations and through-material applications in thick concrete or masonry
• Faster drilling with less effort - the chisel-shaped head and high-volume multi-flute spiral work together to clear concrete dust continuously, reducing resistance and keeping drilling speed high so jobs get done more efficiently
• Trusted Simpson quality, verified to industry standards - manufactured to meet ANSI Standard B212.15 compliance requirements, this bit reflects Simpson's commitment to precise tolerances and consistent performance across their complete line of drilling and demolition tools

Frequently Asked Questions

What type of drill is this bit compatible with?

The Simpson MDPL03718 features an SDS-plus shank, making it compatible with any standard SDS-plus shank rotary hammer drill.

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

This drill bit has an overall length of 18 in. and a maximum drilling depth of 16 in.

What materials and construction features contribute to the durability of this drill bit?

The bit body is made from a chromium-nickel-molybdenum steel alloy for hammering quality and extended service life. Uniformly brazed carbide inserts provide longer bit life, and heat-treatment procedures combined with a shot-peened finish increase surface hardness, improve resistance to bending forces, and reduce wear during drilling.

What standards does this drill bit conform to, and what design features improve drilling efficiency?

The Simpson MDPL03718 conforms to ANSI Standard B212.15. Its 2-cutter chisel-shaped head penetrates material efficiently and directs concrete dust into the high-volume, multi-flute spiral, which quickly channels dust out of the hole to improve drilling speed.
