Pickup available at IES - Mississauga
Usually ready in 4 hours
The Greenlee GSB01 is a compact multi-hole step bit designed for electricians who need precise, clean holes from 1/8" to 1/2" through steel enclosures, aluminium sheet, copper bus, and plastic laminates without swapping bits — ideal for device knockout work, device box installations, and panel wiring on tight residential and light commercial jobs. With 13 drill stages across a compact size range, the patented split-step design and progressive cutting edges optimise chip load and torque efficiency to reduce stalling and deliver more holes per battery charge. A durable split-point tip, improved double-flute chip evacuation, and laser-marked sizing ensure consistent precision and fast identification in confined work areas.
