Milwaukee 11/16" x 16" x 21" MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3926

ENGINEERED FOR UNYIELDING ENDURANCE IN REINFORCED CONCRETE

When structural integrity demands high-volume drilling through heavy rebar and hard aggregate, the MX4™ 4-Cutter SDS Max bit is the professional’s solution for minimizing downtime. Featuring a solid head carbide construction, this bit is designed to withstand the thermal stress of continuous drilling while the integrated rebar guards prevent the catastrophic lock-ups that often plague standard 2-cutter bits. The precision-ground sharp centering tip ensures exact spot drilling, crucial for maintaining layout accuracy on large-scale masonry and concrete decking projects. By optimizing the flute geometry for rapid dust extraction, this bit not only runs cooler but also maximizes the efficiency of your cordless SDS Max hammers, delivering significantly more holes per charge.

• / Solid head carbide provides up to 5x longer service life in high-density concrete with rebar reinforcement.
• / Advanced 4-cutter geometry eliminates binding and lock-up when encountering rebar, protecting the user and the tool.
• / Optimized variable flutes accelerate dust removal to reduce heat buildup and increase drilling speed by up to 15%.
• / Integrated wear mark indicators provide a clear visual cue for when the bit no longer meets ANSI B212.15 requirements for anchor fitment.
