Product Description
Key Features
- Uniformly Brazed Carbide Inserts: Precision brazing process delivers consistent carbide bonding for longer bit life and reliable performance over repeated use.
- Self-Centering Tips: Engineered tip geometry ensures accurate hole placement on first contact, reducing drift and improving positioning precision.
- Chromium-Nickel-Molybdenum Steel Alloy Body: Premium alloy construction ensures superior hammering quality and an extended service life under high-impact conditions.
- Heat-Treatment & Shot-Peened Finish: Advanced heat-treatment procedures combined with a shot-peened surface finish increase surface hardness, improve drilling speed, reduce drill bit wear, and enhance resistance to bending forces.
- ANSI Standard B212.15 Compliant: Drill bit conforms to ANSI Standard B212.15, ensuring dimensional accuracy and interoperability with standard SDS-max rotary hammers.
- High-Volume Multi-Flute Spiral: The double-helix, high-volume flute design rapidly channels concrete dust out of the hole, keeping the cutting zone clear and improving overall drilling speed.
- 4 x 90 deg. Quad-Head Geometry: The unique four-cutting-edge, 90 deg. head geometry crushes through rebar and actively prevents the bit from sticking in reinforced concrete - a critical advantage in structural drilling.
- Patented Reinforced Core Flute: The high-performance reinforced core flute maximizes energy transfer from the hammer to the tip for peak efficiency and reduced operator fatigue.
- SDS-Max Shank: Compatible with all SDS-max rotary hammers for a secure, tool-free bit change and optimal power transmission.

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. It also conforms to ANSI Standard B212.15, ensuring dimensional accuracy and interoperability with standard SDS-max rotary hammer tools.
- What is the maximum drilling depth this bit can achieve?
- The Simpson MDMX11236Q has an overall length of 36 inches and a maximum drilling depth of 31 inches, providing ample reach for deep anchor holes and structural drilling applications.
- Can this drill bit cut through rebar in reinforced concrete?
- Yes. The quad-head design features a 4 x 90 deg. head geometry specifically engineered to crush through rebar and prevent the bit from sticking in reinforced concrete, making it well-suited for structural drilling applications where rebar may be encountered.
- What materials and manufacturing processes are used to ensure durability?
- The bit body is constructed from a chromium-nickel-molybdenum steel alloy for superior hammering quality and extended service life. It also undergoes heat-treatment procedures and a shot-peened finish to increase surface hardness, improve drilling speed, reduce wear, and enhance resistance to bending forces. The carbide inserts are uniformly brazed for consistent bonding and longer bit life.
