Product Description
The Simpson MDPL12518Q 1-1/4 in. x 18 in. SDS-plus Quad-Head Shank Drill Bit is a premium, professional-grade carbide-tipped drill bit engineered by Simpson Strong-Tie to the highest industry standards. Designed for demanding drilling applications in reinforced concrete and masonry, this bit features a proprietary 4 x 90 deg. Quad Head geometry that crushes through rebar and prevents sticking, delivering exceptional drilling speed and extended service life in the most challenging 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
- 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 and optimal hammer energy transfer
- Designed to meet precise tolerance requirements for consistent, accurate drilling

Frequently Asked Questions
- What makes the Quad Head design on the MDPL12518Q superior for reinforced concrete drilling?
- The 4 x 90 deg. Quad Head geometry is engineered to crush through rebar rather than binding against it, which prevents the bit from sticking in reinforced concrete. This design allows continuous drilling progress even when rebar is encountered, improving both safety and productivity on reinforced concrete applications.
- How deep can the Simpson MDPL12518Q drill?
- The MDPL12518Q has a maximum drilling depth of 16 in., with an overall bit length of 18 in. and a diameter of 1-1/4 in., making it well suited for deep anchor and fastening applications in concrete and masonry.
- How does the multi-flute spiral design benefit drilling performance?
- The high-volume, multi-flute spiral design rapidly channels concrete dust and debris out of the hole as drilling progresses. This efficient dust evacuation reduces clogging, minimizes heat buildup, and improves overall drilling speed, contributing to longer bit life and cleaner, more accurate holes.
