Milwaukee SDS Plus 4-Cutter MX4 1/2" x 4" x 6" Drill Bit 48-20-7371
REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY
When drilling into high-PSI concrete laced with rebar, the primary failure point for most accessories is heat and mechanical binding. The Milwaukee MX4™ 4-Cutter design is engineered to eliminate the "lock-up" common in 2-cutter bits, utilizing a solid head carbide that maintains structural integrity under extreme friction. By incorporating rebar guards and variable flute geometry, this bit optimizes dust evacuation, which significantly reduces thermal stress on the carbide. For professionals running cordless platforms like the M18 FUEL™ SDS Plus Rotary Hammers, the reduced resistance means up to 20% more holes per battery charge, maximizing jobsite ROI and tool longevity.
- / Solid head carbide delivers up to 5X longer life in heavy-duty concrete and rebar applications.
- / 4-Cutter geometry prevents binding and lock-up when encountering steel reinforcement, reducing downtime and user fatigue.
- / Sharp centering tip provides exact spot drilling on concrete and metal decking, preventing bit walk for precise anchor placement.
- / Wear mark indicator allows for instant visual verification of ANSI B212.15 compliance for critical anchoring requirements.
