Milwaukee SDS PLUS 4CT MX4™ 5/16" X 10" X 12"

Milwaukee SDS-PLUS MX4 5/16" X 10" X 12" drill bits feature a solid head carbide design that delivers up to 5 times longer life when drilling through concrete with rebar. These drill bits are engineered with rebar guards for maximum durability in tough aggregate and rebar environments. The innovative 4-cutter design prevents lock-up, reducing downtime and increasing efficiency. A sharp centering tip ensures precise spot drilling in both concrete and metal decking. Variable flutes efficiently remove dust, reduce heat buildup, and provide 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 standards. These MX4 4-cutter drill bits are ideal for concrete with rebar and masonry applications, offering reliable performance and extended durability. Model Number: 48-20-7344
