Product Description
Key Features
- Quad-Head Dual-Cutter Design: The high-volume, double-helix quad-head bit features a patented, high-performance, reinforced core flute to maximize energy transfer and improve drilling speed and durability.
- 4 x 90 deg. Head Geometry: Crushes through rebar and prevents sticking in reinforced concrete, maintaining forward progress even in the toughest substrates.
- Uniformly Brazed Carbide Inserts: Precision brazing of carbide inserts ensures consistent contact and longer bit life across the full working depth.
- Self-Centering Tips: Delivers accurate hole placement from first contact, reducing walk and improving finished hole quality.
- Chromium-Nickel-Molybdenum Steel Alloy Body: High-grade alloy construction ensures superior hammering quality and extended service life under repeated impact loads.
- Heat-Treatment & Shot-Peened Finish: Proprietary heat-treatment procedures and a shot-peened surface finish increase surface hardness and drilling speed, reduce drill bit wear, and improve resistance to bending forces.
- High-Volume Multi-Flute Spiral: Rapidly channels concrete dust away from the hole to improve drilling speed and prevent clogging.
- Reduced Vibration & Noise: Proprietary flute geometry optimizes impact energy transfer from the rotary hammer into the drill bit tip, reducing stress, vibration, and noise on the operator.
- ANSI Compliant: Drill bit conforms to ANSI Standard B212.15 for dimensional accuracy and performance consistency.
- SDS-Max Shank: Compatible with SDS-max rotary hammers for secure, tool-free bit changes and positive drive engagement.

Frequently Asked Questions
- What shank type does this drill bit use, and which tools is it compatible with?
- This drill bit features an SDS-max shank, making it compatible with SDS-max rotary hammers. The SDS-max connection is designed for larger, more powerful rotary hammers typically used in heavy-duty concrete and masonry drilling applications.
- What is the drilling depth and overall length of this bit?
- The Simpson MDMX13717Q has an overall length of 17 inches and a maximum drilling depth of 12 inches. The diameter is 1-3/8 inches.
- Can this drill bit be used in reinforced concrete with rebar?
- Yes. The quad-head design features a 4 x 90 deg. head geometry that is specifically engineered to crush through rebar and prevent sticking in reinforced concrete, allowing the bit to maintain forward progress even in heavily reinforced substrates.
- What materials and manufacturing processes are used to ensure durability?
- The bit body is made from a chromium-nickel-molybdenum steel alloy for superior hammering quality and extended service life. It also undergoes proprietary heat-treatment procedures and a shot-peened finish to increase surface hardness, improve resistance to bending forces, and reduce wear. Carbide inserts are uniformly brazed for consistent contact and longer bit life. The bit conforms to ANSI Standard B212.15.
