Greenlee 1" Cobalt Step Bit (#8), Model 30008C
The Greenlee 30008C is a professional-grade cobalt step bit engineered for electricians and contractors who need to drill clean, precise holes through tough materials on the job site. Built from Cobalt High-Speed Steel (HSS), this step bit outlasts standard HSS bits when cutting through stainless steel, mild steel, copper, brass, aluminum, fiberglass, plastic, wood, and laminates — making it one of the most versatile bits in any electrician’s kit. Whether you’re punching knockouts in electrical panels, drilling through enclosures, or sizing conduit entry holes, the 30008C delivers consistent, burr-free results from 1/2" up to 1-1/8" in a single tool.
Key Features
| Cobalt HSS Construction | Cobalt High-Speed Steel provides maximum tool life when cutting stainless steel and other hard metals that wear out standard bits quickly. |
| Multi-Material Cutting | Cuts stainless steel, mild steel, copper, brass, aluminum, fiberglass, plastic, wood, and laminates — one bit for virtually every job site material. |
| Step Design | Stepped profile drills multiple hole sizes in a single pass, eliminating the need to swap bits and speeding up panel and enclosure work. |
| Hexagonal Shank | Hex shank design prevents slipping in the chuck and is compatible with standard drill chucks and quick-change systems. |
