Milwaukee Tool introduces a new line of step bits designed to deliver jam-free performance, optimized for cordless drills in high speed. With Milwaukee’s Rapid Strike tip design, the step bits prevent bit walking and deliver fast, accurate starts that generate less heat. The new bits include a black-oxide coating for enhanced durability, hole quality and bit life. Each bit also has laser-engraved reference marks visible while drilling. The three-flat Secure-Grip shank ensures a solid connection with the drill chuck.
