SDS Plus 4CT MX4™ 1-1/4" X 16" X 18"

The MILWAUKEE® MX4™ 4-Cutter SDS PLUS Rotary Hammer Drill Bits deliver up to 5x longer life in concrete with rebar. Solid head carbide delivers that extended life in tough materials while engineered rebar guards provide maximum durability in hard aggregate and rebar to protect cutting geometry under repeated impact. The MX4™ 4-cutter bits with sharp centering tips are designed for exact spot drilling in concrete and metal decking, and the 4-cutter design prevents lock-up in rebar, reducing downtime. Variable flutes remove dust faster, reduce heat and deliver up to 20% more holes per battery charge, extending work between charges and improving efficiency. A wear mark indicator on each drill bit shows you when they no longer meet the ANSI B212.15. Ideal for concrete with rebar and masonry, these MILWAUKEE® MX4™ 4-Cutter Drill Bits fit all SDS PLUS rotary hammers and are available as single bits, bulk packs, or drill bit kits in a variety of sizes.
