Milwaukee MX4 4-cutter SDS-Plus carbide bits are Milwaukee's premium concrete drilling bits, built with a four-cutting-edge carbide head for precise, fast holes in the toughest masonry, including concrete with rebar. The extra cutting edges power through hard aggregate and reinforcement that can slow or deflect a standard 2-cutter bit, keeping you on target and reducing wear.

Great Lakes Power Tools carries Milwaukee MX4 bits in a range of diameters and lengths for your SDS-Plus rotary hammer. Whether you're setting anchors in reinforced concrete or drilling heavy masonry all day, these premium 4-cutter bits deliver accuracy and long life.
