The Simpson 1/2 in. x 18 in. SDS-plus Shank Drill Bit is a premium-quality, professional-grade carbide-tipped rotary hammer bit engineered for demanding concrete drilling applications. Built to precise tolerance requirements and conforming to ANSI Standard B212.15, this bit incorporates proprietary design features that work together to enhance durability, improve drilling speed, and reduce user effort - making it a reliable choice for anchoring, fastening, and structural drilling tasks where consistent, accurate holes are critical.

Key Features

• Uniformly brazed carbide inserts - even, secure bonding across the cutting edge extends bit life and maintains consistent cutting performance over repeated use
• Chromium-nickel-molybdenum steel alloy body - this high-strength alloy construction ensures hammering quality and extended service life under the repeated impact forces of rotary hammer drilling
• Heat-treatment procedures and shot-peened finish - these manufacturing steps increase surface hardness, reduce drill bit wear, improve resistance to bending forces, and contribute to faster drilling speed
• Chisel-shaped drill-bit head - penetrates material efficiently and directs concrete dust into the multi-flute spiral, keeping the cutting zone clear for faster, cleaner progress
• High-volume, multi-flute spiral - quickly channels concrete dust out of the hole during drilling, reducing friction and improving overall drilling speed
• 2-cutter head design - delivers focused, aggressive cutting action suited to hardened concrete and masonry
• SDS-plus shank - fits the industry-standard SDS-plus rotary hammer system for quick, tool-free bit changes and a secure, locked-in connection during operation
• ANSI Standard B212.15 compliance - confirms the bit meets established dimensional and performance standards, ensuring reliable fit and predictable results

Why This Product

• Professional-grade construction built to last - the combination of uniformly brazed carbide inserts and a chromium-nickel-molybdenum steel alloy body means this bit holds up to the repeated impact stress of heavy-duty concrete drilling, reducing the frequency of bit replacement on the job
• Engineered for speed and efficiency - the chisel-shaped head and high-volume multi-flute spiral work together to clear concrete dust continuously, so the bit cuts faster with less resistance and less effort from the operator
• Designed to Simpson's proprietary tolerances - manufactured in Germany to the highest industry standards and verified against ANSI Standard B212.15, this bit delivers the dimensional accuracy needed for anchor installations and other applications where hole diameter and depth precision matter
• Versatile reach for deep-hole applications - with a 16 in. drilling depth and an 18 in. overall length, this bit handles deep concrete anchoring and through-slab drilling tasks that shorter bits simply cannot reach

Frequently Asked Questions

What shank type does the MDPL05018 use, and which rotary hammers are compatible?

The MDPL05018 features an SDS-plus shank, which is the industry-standard connection system compatible with SDS-plus rotary hammer drills. The SDS-plus design allows for quick, tool-free bit changes while maintaining a secure, locked-in fit during operation.

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

The MDPL05018 has a drilling depth of 16 in. and an overall length of 18 in., with a 1/2 in. diameter. The additional length beyond the drilling depth accommodates the shank and allows for secure chuck engagement.

What makes the carbide tip and body construction of this bit durable for heavy-duty use?

The bit features uniformly brazed carbide inserts for longer bit life, and its body is constructed from a chromium-nickel-molybdenum steel alloy that ensures hammering quality and extended service life. Heat-treatment procedures and a shot-peened finish further increase surface hardness, reduce drill bit wear, and improve resistance to bending forces.

How does the bit 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 out of the hole, which improves drilling speed and helps maintain a clean, efficient bore through the material.
