The Simpson Strong-Tie MDPL05018 1/2 in. x 18 in. SDS-plus Shank Drill Bit is a premium-quality, professional-grade carbide-tipped drill bit engineered to deliver superior performance in concrete drilling applications. Featuring a 2-cutter head design, a 16 in. drilling depth, and an 18 in. overall length, this bit is built to the highest industry standards and designed to meet precise tolerance requirements - incorporating proprietary features that enhance durability and drilling speed while improving ease of use.

Key Features

• Uniformly brazed carbide inserts result in longer bit life
• 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 for efficient material penetration
• SDS-plus shank for secure, tool-free bit changes in compatible rotary hammers
• Premium-quality, professional-grade construction manufactured to the highest industry standards for Simpson Strong-Tie

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.
