Key Features

• Uniformly Brazed Carbide Inserts - Consistent, high-quality brazing results in longer bit life and superior wear resistance across demanding applications.
• Self-Centering Tips - Ensures accurate hole placement from the first contact, reducing the need for repositioning and improving job-site efficiency.
• Chromium-Nickel-Molybdenum Steel Alloy Body - Premium steel alloy construction provides outstanding hammering quality and an extended service life under continuous heavy use.
• Heat-Treatment & Shot-Peened Finish - Specialized heat-treatment procedures and a shot-peened surface finish increase surface hardness, boost drilling speed, reduce drill bit wear, and improve resistance to bending forces.
• High-Volume, Multi-Flute Spiral - Quickly channels concrete dust out of the hole to maintain drilling speed and prevent clogging.
• Proprietary Flute Geometry - Reduces vibration and optimizes impact energy transfer from the rotary hammer into the drill bit tip, enhancing drilling speed and durability while reducing noise, stress, and vibration on the operator.
• 4 x 90 deg. Head Geometry - Crushes through rebar and prevents the bit from sticking in reinforced concrete, keeping work moving without interruption.
• 2-Cutter Head - Designed to improve durability and drilling speed throughout the bit's service life.
• ANSI Standard B212.15 Compliant - Conforms to established industry tolerance and quality standards for SDS-max drill bits.
• SDS-Max Shank Compatibility - Fits all current and older SDS-max rotary hammers for broad tool compatibility on the job site.

Frequently Asked Questions

What type of rotary hammer is this drill bit compatible with?

This drill bit features an SDS-max shank, which fits all current SDS-max rotary hammers. The SDS-max shank design is intended for larger, more powerful rotary hammers typically used in heavy-duty concrete and masonry applications.

What are the key dimensions and drilling depth of this bit?

The Simpson MDMX05013 has a 1/2 in. diameter and an overall length of 13 in. The maximum drilling depth is 7-1/2 in.

Can this drill bit be used in reinforced concrete containing rebar?

Yes. The bit features a 4 x 90 deg. head geometry specifically designed to crush through rebar and prevent the bit from sticking in reinforced concrete, allowing work to continue without interruption.

What materials and quality standards does this drill bit meet?

The bit body is constructed from a chromium-nickel-molybdenum steel alloy, which is heat-treated and shot-peened to increase surface hardness and resistance to bending forces. The carbide inserts are uniformly brazed for longer bit life. The drill bit conforms to ANSI Standard B212.15, ensuring compliance with established industry tolerance and quality standards for SDS-max drill bits.
