The Greenlee 1-1/8" carbide-tipped hole cutter is designed for electricians cutting clean, burr-free holes in stainless steel, mild steel, aluminum, copper, brass, fiberglass, and plastics — no oil required. Its quick-change push-and-turn connection makes swapping cutter sizes fast and tool-free, keeping conduit work moving efficiently on the job site. A flange stop prevents over-drilling and the slug ejector spring ensures quick slug clearance between cuts.
