Product Description
Key Features
- Uniformly Brazed Carbide Inserts - Precision brazing delivers consistent carbide contact for longer bit life and reduced premature wear.
- Self-Centering Tips - Engineered tip geometry ensures accurate hole placement from the first strike, minimizing bit walking.
- Chromium-Nickel-Molybdenum Steel Alloy Body - Premium CrNiMo alloy construction ensures exceptional hammering quality and an extended service life under continuous heavy-duty use.
- Heat-Treated & Shot-Peened Finish - Advanced heat-treatment procedures combined with a shot-peened surface finish increase surface hardness, boost drilling speed, reduce bit wear, and improve resistance to bending forces.
- ANSI Standard B212.15 Compliant - Drill bit conforms to ANSI Standard B212.15, ensuring dimensional accuracy and reliable performance.
- High-Volume, Multi-Flute Spiral - Rapidly channels concrete dust away from the hole to improve drilling speed and prevent clogging.
- 4 x 90 deg. Quad-Head Geometry - The four-cutter, 90-degree head configuration crushes through rebar and prevents sticking in reinforced concrete.
- Double-Helix Design - The high-volume, double-helix flute geometry maximizes energy transfer from the rotary hammer to the bit tip for faster, more efficient drilling.
- SDS-Max Shank Compatibility - Fits all current and older SDS-max rotary hammers from major tool brands.

Frequently Asked Questions
- What shank type does this drill bit use, and will it fit my rotary hammer?
- This drill bit features an SDS-max shank, which is compatible with all current and older SDS-max rotary hammers from major tool brands. It is not compatible with SDS-plus or standard chuck rotary hammers.
- What is the maximum drilling depth this bit can achieve?
- The Simpson MDMX10623Q has an overall length of 23 inches and a maximum drilling depth of 18 inches. The additional length beyond the drilling depth accommodates the SDS-max shank engagement in the rotary hammer chuck.
- Can this drill bit be used in reinforced concrete containing rebar?
- 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. The chromium-nickel-molybdenum steel alloy body and uniformly brazed carbide inserts further support durability under these demanding conditions.
- What material is the bit body made from, and are there any quality or standards certifications?
- The bit body is constructed from a chromium-nickel-molybdenum steel alloy, which is heat-treated and shot-peened to increase surface hardness, improve drilling speed, reduce wear, and enhance resistance to bending forces. The drill bit conforms to ANSI Standard B212.15, ensuring dimensional accuracy and reliable performance.
