Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3958

REINFORCED CONCRETE DOMINANCE

When managing a tool fleet across high-density jobsites, the consumable bit is often the critical failure point. The Milwaukee MX4™ 4-Cutter SDS Max bits are engineered to solve the ROI equation by eliminating the primary cause of bit destruction: rebar strikes. By utilizing a solid-head carbide design rather than standard brazed inserts, these bits maintain structural integrity under extreme thermal loads and high-torque impacts, ensuring your crew hits the required depth without the downtime of clearing jammed steel or replacing shattered bits.

• / Solid Head Carbide: Delivers up to 5x longer life in high-PSI concrete with heavy rebar reinforcement compared to standard bits.
• / Integrated Rebar Guards: Designed to deflect high-impact energy away from the bit’s core, preventing catastrophic failure in hard aggregate.
• / 4-Cutter Geometry: Prevents binding and lock-up when striking rebar, protecting both the operator and the rotary hammer's internal clutch.
• / Optimized Flute Design: Rapidly ejects dust and debris to reduce heat friction, resulting in 15% more holes per battery charge on M18 FUEL systems.
• / Wear Mark Indicators: Provides visual verification of ANSI B212.15 compliance, ensuring precision anchor fitment throughout the bit's lifecycle.
