step drills are ideal for drilling in the following materials: - alloyed and unalloyed sheets, profiles, and pipes. - copper, brass and aluminum. -stainless steel. -plastic. - maximum material thickness 4 mm. - The use of coolant is recommended to increase service life. - electricians: drilling panels and switch cabinets for cable installations. - SHK: access holes in pipes and lines. - metalworker: dilling various diameters and enlarging holes. - automotive: holes for cable installations (cell phones, antennas, cable routing). - maintenance: various applications. Step drills save costs compared to conventional drills: - one drill for different diameters. - the optimal solution for enlarging holes. - break-proof as standard metal drill. - easy centering. - clean and burr-free holes. splinter-free drilling in plastic. MILWAUKEE® advantages. center punching, drilling, and deburring in one step. RAPID STRIKE™ drill tip for easier centering. A special drill tip and a special step geometry enable vibration-free drilling. lower risk of tilting at high speeds. optimized 2-spiral geometry with sharpened edges for up to 2x faster drilling progress. made from special steel with a black oxide coating for up to 4x longer operating life. optimized for use with cordless tools. laser marking of the diameters. Each step is ground on the back for optimal drilling feed and automatic deburring. shaft with 3 clamping surfaces for secure hold in the drill chuck and optimum power transmission
