The Greenlee 1-3/8" carbide-tipped hole cutter is built for electricians who need clean, burr-free holes in stainless steel, mild steel, aluminum, copper, brass, fiberglass, and plastics — with no oil required. Its quick-change push-and-turn connection allows fast cutter swaps without re-chucking, reducing downtime on busy job sites. A flange stop prevents over-drilling while the slug ejector spring keeps slugs clearing quickly.
