Product Description
Key Features
- Uniformly Brazed Carbide Inserts - Precision brazing process results in longer bit life and consistent cutting performance.
- Self-Centering Tips - Ensures accurate hole placement from the first strike, reducing wasted effort and material.
- Chromium-Nickel-Molybdenum Steel Alloy Body - High-grade alloy construction ensures superior hammering quality and extended service life under heavy use.
- Heat-Treatment & Shot-Peened Finish - Advanced surface hardening procedures increase surface hardness and drilling speed, reduce drill bit wear, and improve resistance to bending forces.
- ANSI Standard B212.15 Compliant - Drill bit conforms to ANSI Standard B212.15 for reliable, standardized performance.
- High-Volume Multi-Flute Spiral - Quickly channels concrete dust out of the hole to improve drilling speed and reduce clogging.
- 4 x 90 deg. Head Geometry - Crushes through rebar and prevents bit sticking in reinforced concrete for uninterrupted drilling.
- 2-Cutter Head Design - All features of this design are engineered to improve both durability and drilling speed.
- SDS-Max Shank - Compatible with all current and older SDS-max rotary hammers for versatile use across major tool brands.
- Made in Germany - Manufactured to the highest industry standards for professional-grade reliability.

Frequently Asked Questions
- What type of rotary hammer is this drill bit compatible with?
- This drill bit features an SDS-max shank, making it compatible with all current and older SDS-max rotary hammers across major tool brands.
- What is the maximum drilling depth this bit can achieve?
- The Simpson MDMX05021 has an overall length of 21 in. and a maximum drilling depth of 15-1/2 in.
- Can this drill bit be used in reinforced concrete containing rebar?
- Yes. The 4 x 90 deg. head geometry is specifically designed to crush through rebar and prevent the bit from sticking in reinforced concrete, allowing for uninterrupted drilling.
- What materials and manufacturing processes give this bit its durability?
- The bit body is constructed from a chromium-nickel-molybdenum steel alloy for superior hammering quality and extended service life. It also features uniformly brazed carbide inserts for longer bit life, and undergoes heat-treatment procedures and a shot-peened finish to increase surface hardness, reduce wear, and improve resistance to bending forces.
