Milwaukee 48-20-3930 3/4in x 7in x 13in MX4 4-Cutter SDS-MAX Rotary Hammer Drill Bit

Description

Built for reinforced concrete and heavy masonry drilling, the Milwaukee MX4 4-Cutter SDS-MAX Rotary Hammer Drill Bit (3/4in x 7in x 13in) delivers exceptional strength, accuracy, and long-term performance. Its solid carbide head is engineered for extended wear life, while the precision centering tip enables accurate hole starts with reduced wandering. The advanced 4-cutter geometry helps eliminate bit binding and cut interruptions, and the optimized flute design rapidly clears dust to lower heat buildup and maintain consistent drilling speed—making it ideal for demanding jobsite applications involving rebar and dense concrete.
