Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 1"X16"X18"

Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 1"X16"X18"

The 48-20-7246 Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit (1" x 16" x 18") is a premium SDS-Plus rotary hammer bit built for high-performance drilling in concrete—especially concrete with rebar. Its solid head carbide and rebar guards provide 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 identify end-of-life when the bit no longer meets ANSI requirements for anchor fit.
