MilwMilwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 1-1/8"X8"X10"

Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 1-1/8"X8"X10"

The 48-20-7250 Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit (1-1/8" x 8" x 10") is a premium SDS-Plus rotary hammer bit engineered for fast, accurate drilling in concrete—especially concrete with rebar. Its solid head carbide and rebar guards deliver durability in hard aggregate, while the 4-cutter design helps prevent rebar lock-up to reduce downtime. Variable flutes clear dust faster to reduce heat and can deliver up to 20% more holes per battery charge, and the wear mark indicator helps you know when the bit no longer meets ANSI requirements for anchor fit.
