5 PC SDS Plus 4CT MX4™ Set

The Milwaukee 48-20-7498 5-Piece SDS Plus 4CT MX4™ Set is a professional masonry drill bit kit designed for fast, high-performance drilling in concrete, brick, block, and reinforced concrete with embedded rebar.

Each bit features Milwaukee’s MX4™ solid carbide 4-cutter head, engineered for maximum durability and consistent performance in tough aggregate. The 4-cutter design improves hole accuracy, reduces walking, and significantly increases resistance when encountering rebar compared to traditional 2-cutter bits.

The set includes a range of commonly used sizes for anchor installation and general concrete work, making it a versatile all-in-one kit for contractors and serious users. Each bit also features a breaker-point tip for aggressive material removal and a reinforced flute design that helps clear dust quickly to reduce heat buildup and extend tool life.
