The Greenlee 1-3/4" carbide-tipped hole cutter delivers fast, clean holes in stainless steel, mild steel, aluminum, copper, brass, fiberglass, and plastics — no oil required. The quick-change arbor system lets electricians swap cutter heads in seconds without re-chucking, making it ideal for high-volume conduit work on job sites. A flange stop eliminates over-drilling, and the split-point cobalt steel pilot drill prevents walking for accurate starts every time.
