Product Description
Key Features
- Quad-Head Dual-Cutter Design: High-volume, double-helix quad-head design with a patented, high-performance reinforced core flute maximizes energy transfer and improves both durability and drilling speed.
- Uniformly Brazed Carbide Inserts: Precisely brazed carbide tips provide consistent contact and result in longer bit life across repeated use.
- Self-Centering Tips: Engineered for accurate hole placement, reducing the need for repositioning and improving overall productivity.
- 4 x 90 deg. Head Geometry: Crushes through rebar and prevents sticking in reinforced concrete, making it ideal for heavily reinforced substrates.
- Chromium-Nickel-Molybdenum Steel Alloy Body: Ensures superior hammering quality and extended service life under high-impact conditions.
- Heat-Treatment & Shot-Peened Finish: Increases surface hardness, improves drilling speed, reduces drill bit wear, and improves resistance to bending forces.
- High-Volume Multi-Flute Spiral: Quickly channels concrete dust from the hole to improve drilling speed and reduce clogging.
- SDS-max Shank: Compatible with SDS-max rotary hammers for secure, tool-free bit changes and reliable torque transfer.
- ANSI Standard B212.15 Conformance: Drill bit conforms to ANSI Standard B212.15 for assured dimensional and performance consistency.
- Reduced Operator Fatigue: Proprietary flute geometry reduces noise, stress, and vibration transmitted to the operator during prolonged use.

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 allows for secure, tool-free bit changes and reliable torque transfer during high-impact drilling applications.
- What are the dimensions and maximum drilling depth of this bit?
- The Simpson MDMX20023Q has a 2-inch diameter and an overall length of 23 inches. The maximum drilling depth is 18 inches, making it well suited for deep-hole applications in concrete and reinforced concrete.
- Can this drill bit be used in reinforced concrete containing rebar?
- Yes. The quad-head design features 4 x 90 deg. head geometry that is specifically engineered to crush through rebar and prevent the bit from sticking in reinforced concrete, making it a strong choice for heavily reinforced substrates.
- What materials and standards does this drill bit conform to?
- The drill bit body is made from a chromium-nickel-molybdenum steel alloy, which ensures superior hammering quality and extended service life. The carbide inserts are uniformly brazed for consistent performance and longer bit life. The bit also conforms to ANSI Standard B212.15 for assured dimensional and performance consistency.
