This Greenlee 8-piece quick-change carbide-tipped hole cutter set covers seven hole sizes from 7/8" to 2-1/2" and cuts stainless steel, mild steel, iron, copper, brass, aluminium, fibreglass, and plastic sheet — making it a versatile solution for knockout work across enclosures, panels, and junction boxes on the job site. The Quick-Change arbor system lets you swap cutter heads with a simple push and turn using the same arbor across all sizes, while a flange stop prevents over-drilling and an ejector spring (on sizes over 3/4") makes slug removal easier. Improved carbide quality delivers greater durability and longer life, and a replaceable cobalt-steel pilot drill with split-point tip ensures accurate, walk-free starts every time.
