Milwaukee 48-20-7200 MX4™ SDS PLUS 4-Cutter Rotary Hammer Bit

The Milwaukee 48-20-7200 MX4™ is a 4-cutter SDS PLUS rotary hammer bit engineered for high-performance drilling in reinforced concrete and masonry. It features a solid carbide head with quad-cut geometry designed to minimize lock-up when encountering rebar and deliver consistent hole quality over extended use.

Product Features

• 4-Cutter Carbide Tip: Solid head geometry provides balanced drilling and reduces bit jamming in rebar.
• Rebar Guards: Added reinforcement at critical points to reduce head damage in embedded steel.
• Centering Tip: Precision-ground point enables accurate spot drilling and reduces bit wander at start-up.
• Variable Flute Profile: Improves dust extraction and lowers internal bit temperature, extending battery runtime in cordless tools.
• Wear Mark Indicator: Integrated reference line indicates when the bit no longer meets ANSI hole diameter tolerances.

Technical Specifications

• Connection Type: SDS PLUS
• Bit Diameter: 1/2 inch (specific to model 48-20-7200)
• Drilling Applications: Concrete, block, brick, and metal decking with embedded rebar
• Tip Material: Solid carbide
• Design: 4-cutter head with rebar protection and optimized flute geometry

Recommended Usage

This bit is designed for use in SDS PLUS rotary hammer drills when drilling anchor or clearance holes in concrete and other aggregate materials. Suitable for both corded and cordless rotary hammers operating within SDS PLUS standards.

Installation Guidance

Users should be familiar with hammer drilling best practices and appropriate PPE. Always inspect the bit for wear, use within the tool's rated RPM range, and avoid prolonged dry contact with embedded steel. Replace the bit once the wear mark is no longer visible to maintain ANSI hole tolerance compliance.
