Milwaukee SDS-Plus 4-Cutter MX4™ 1/2 in. x 6 in. Rotary Hammer Drill Bit (48-20-7371)

The Milwaukee SDS-Plus 4-Cutter MX4™ 1/2 in. x 6 in. Rotary Hammer Drill Bit (Model 48-20-7371) is engineered for durability and precision, providing up to 4x longer life in rebar and 20% more holes per charge in cordless rotary hammers. This robust bit is built with a solid carbide 4-cutter tip that ensures long-lasting performance and enhanced strength in demanding applications like drilling through rebar and hard aggregate.

The MX4™ drill bit features a 90° 4-cutter head design with reinforced rebar guards, which effectively resists wear and increases durability in tough conditions. A variable flute design maximizes debris extraction, improving efficiency and extending battery life in cordless rotary hammers. For pinpoint accuracy, the MX4™ is equipped with a centering tip that enables precise spot drilling, and a wear mark indicator that shows when the bit no longer meets ANSI diameter standards.
