Designed to produce 5 hole sizes from 7/8" (22.2 mm) to 1-3/8" (34.9 mm), this black oxide step drill bit works through metal and plastic with a straight flute design. It utilizes a Rapid Strike™ tip for accurate starts and reduced heat, extending the life of the high speed steel. Additionally, the 3-flat Secure-Grip™ shank prevents slipping within a 3/8" (9.5 mm) drill chuck during operation.
