Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 3/8"X10"X12"

Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 3/8"X10"X12"

The Milwaukee 48-20-7354 MX4™ SDS PLUS 4-Cutter Rotary Hammer Drill Bit (3/8" × 10" × 12") is engineered for fast, precise drilling in concrete, masonry, and concrete with rebar. Featuring a solid carbide head with a 4-cutter design, this bit delivers up to 5× longer life in reinforced concrete while helping prevent lock-up when encountering rebar. Rebar guards increase durability in hard aggregate, while a sharp centering tip ensures accurate spot drilling in concrete and metal decking. Variable flute geometry removes dust quickly, reducing heat and delivering up to 20% more holes per battery charge, making it a dependable bit for demanding rotary hammer applications—because drilling into rebar is challenging enough without your bit calling it quits early.
