The MILWAUKEE SDS-MAX 4-Cutter MX4 1-1/8\" X 17\" X 21\" Drill Bits feature carbide heads that deliver up to 4x longer life in concrete with rebar. Engineered with rebar guards to provide maximum durability in hard aggregate and rebar. MX4 4-Cutter bits are designed with sharp centering tips for exact spot drilling in concrete. The integrated 4-cutter design prevents lock-up in rebar, reducing downtime. Variable flutes remove dust faster, reducing heat and delivering up to 15% more holes per battery charge. Wear mark indicator shows users the end of life when the bits no longer meet the ANSI requirement. The Milwaukee MX4 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications.
