Milwaukee SDS-MAX MX4 7/8" X 31" X 36" drill bits are engineered to deliver exceptional performance and durability for concrete and masonry applications. Featuring the MILWAUKEE® MX4™ 4-Cutter design with solid head carbide, these SDS Max rotary hammer drill bits provide up to five times longer life when drilling through concrete with rebar. The bits are equipped with rebar guards to withstand tough aggregate and rebar conditions, ensuring maximum durability. Milwaukee’s sharp centering tips allow for precise spot drilling, while the integrated 4-cutter design prevents lock-up in rebar, minimizing downtime.
