The SDS-Max MX4™ 4-Cut Drill Bits from Milwaukee Tool are built for maximum durability and precision in reinforced concrete. A large carbide tip with patented rebar chamfers and 4 x 90° symmetrical head geometry reduces vibration and prevents jamming when hitting steel. The 130° centering point ensures accurate spot drilling, while reinforced flutes and deep shoulders enable fast dust removal, lower heat build-up, and efficient energy transfer. Enhanced carbide content, wear marks for diameter accuracy, shot-blasted surface treatment, and PGM conformity guarantee long life and consistently precise anchor holes.
