The Greenlee GSB12 is a single-piece multi-hole step bit designed for electricians who need to punch clean, precise holes up to 1-3/8" through steel enclosures, aluminium sheet, copper, wood, and plastic laminates without swapping bits between sizes. The patented split-step design with progressive cutting edges optimises chip load and torque efficiency to reduce stalling and deliver more holes per battery charge — a practical advantage on large panel rough-ins and commercial conduit installations. A durable split-point tip, improved double-flute chip evacuation, and laser-marked sizing ensure consistent performance and quick identification on busy job sites.
