For concrete contractors, electricians, and installers drilling anchor holes in concrete and reinforced concrete using SDS-Plus rotary hammers
Milwaukee SDS-Plus MX4 drill bits are engineered with a solid 4-cutter carbide head, designed for drilling in concrete and reinforced concrete applications. The 4-cutter geometry ensures continuous cutting contact, reducing deviation when encountering rebar and maintaining hole accuracy under load. The solid carbide tip construction increases resistance to wear and impact, extending service life in high-density materials. The flute design is optimised for efficient dust evacuation, supporting consistent drilling speed and reducing binding during deeper hole drilling.
Within the Milwaukee MX4 range, these drill bits are configured for heavy-duty rotary hammer drilling where durability and precision are required. Compared to 2-cutter SDS-Plus bits, the 4-cutter design provides improved hole roundness and reduced vibration, particularly when drilling through reinforced sections. The SDS-Plus shank ensures efficient energy transfer from the hammer mechanism, maintaining drilling performance across both cordless and corded rotary hammers, including Milwaukee M18 SDS-Plus systems. These bits are suitable for anchor fixing, structural installation, and repeated drilling in concrete substrates.
