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
• High-volume, multi-flute spiral quickly channels concrete dust from the hole to improve drilling speed
• 4 x 90 deg. head geometry crushes through rebar and prevents sticking in reinforced concrete
• SDS-plus shank for secure, tool-free bit changes in compatible rotary hammers
• Part of Simpson Strong-Tie's complete line of premium drill bits, core bits, and chisels

Frequently Asked Questions

What type of shank does the MDPL06218Q use, and which rotary hammers is it compatible with?

The MDPL06218Q features an SDS-plus shank, which is the standard quick-release interface used by a wide range of professional and consumer-grade rotary hammers. This shank type allows for tool-free bit changes and secure locking during high-impact drilling operations.

What makes the Quad Head design on this drill bit different from a standard tip?

The 4 x 90 deg. Quad Head geometry is specifically engineered to crush through rebar and prevent the bit from sticking in reinforced concrete. This design distributes cutting force across four contact points, making it significantly more effective than a standard tip when drilling through concrete that contains embedded steel reinforcement.

What is the actual drilling depth of the MDPL06218Q, and how does that differ from its overall length?

The MDPL06218Q has an overall length of 18 in. and a usable drilling depth of 16 in. The difference accounts for the SDS-plus shank portion that seats inside the rotary hammer chuck, which is not part of the active drilling length.

What material is the drill bit body made from, and how is it treated for durability?

The bit body is constructed from a chromium-nickel-molybdenum steel alloy, which is known for its exceptional toughness and resistance to impact stress. It undergoes heat-treatment procedures and receives a shot-peened finish that increases surface hardness, improves resistance to bending forces, and reduces wear during extended use - all while conforming to ANSI Standard B212.15.
