Milwaukee SDS Plus 4CT MX4™ 9/16" X 4" X 6"

Milwaukee SDS-PLUS MX4 9/16" X 4" X 6" drill bits with solid head carbide are designed to deliver up to 5 times longer life when drilling into concrete with rebar. These bits feature a 4-cutter design that prevents lock-up and reduces downtime, while engineered rebar guards provide maximum durability in tough aggregate and rebar conditions. The sharp centering tip ensures precise spot drilling in both concrete and metal decking. Variable flutes efficiently remove dust, reduce heat buildup, and allow for up to 20% more holes per battery charge. Additionally, a wear mark indicator signals when the bit has reached the end of its life and no longer meets ANSI requirements. These MX4 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications, combining durability and performance for demanding jobs. Model Number: 48-20-7381
