The Greenlee Kwik Stepper® 30008C is a professional-grade cobalt step bit engineered for electricians, contractors, and sheet metal workers who need to drill clean, precise holes through tough materials without swapping bits. Covering three hole sizes — 1/2", 7/8", and 1-1/8" — in a single tool, it's ideal for punching conduit entry holes in electrical panels and enclosures, sizing knockouts in sheet metal and junction boxes, and drilling through stainless steel, copper, brass, aluminium, fiberglass, plastic, laminates, and wood. The split point tip starts on contact without walking, while the cobalt HSS cutting edge outlasts standard HSS bits when cutting through 10-gauge stainless steel and other hard metals that quickly wear out lesser tooling. A 3/8" hex shank prevents slipping in the chuck and is compatible with standard drill chucks and quick-change systems, keeping your workflow moving on the job site. The steam oxide finish reduces friction and heat build-up during cutting, extending bit life on demanding applications.
