Milwaukee SDS Max 4CT MX4™ 1-1/8" X 17" X 21"

Milwaukee SDS-MAX MX4 1-1/8" X 16" X 21" drill bits are engineered to deliver exceptional performance and durability for heavy-duty concrete and masonry applications. Featuring MILWAUKEE® MX4™ 4-Cutter SDS Max Rotary Hammer Drill Bits with solid head carbide, these bits provide up to five times longer life when drilling through concrete with rebar. Designed with rebar guards, they offer maximum durability in tough aggregate and rebar environments. The sharp centering tips ensure precise spot drilling in concrete, while the integrated 4-cutter design prevents lock-up in rebar, minimizing downtime. Optimized flutes efficiently remove dust, reducing heat buildup and allowing up to 15% more holes per battery charge. Each bit includes a wear mark indicator to show when it no longer meets ANSI standards, helping you maintain optimal performance on the job. Model Number: 48-20-3966
