The SDS-Max MX4™ 4-Cut Drill Bits from Milwaukee Tool deliver powerful, low-vibration drilling in reinforced concrete thanks to a large carbide tip with patented rebar chamfers and a robust 4 x 90° symmetrical head that prevents jamming on steel. A 130° centering point ensures precise spot drilling, while dynamic secondary cutters and reinforced flute geometry enable faster drilling, efficient dust removal, reduced heat build-up, and improved energy transfer. With increased carbide content, wear marks for diameter accuracy, shot-blasted surface treatment, and PGM conformity, these bits provide long life and consistently precise anchor holes.
