The Greenlee 4-Piece Carbide Hole Cutter Kit (Model 655) is engineered for electricians and contractors who need to cut clean, precise holes through stainless steel, mild steel, and other tough metals quickly and efficiently. Carbide-tipped cutter heads power through hard materials that would wear out standard bi-metal saws, making this kit ideal for enclosure knockouts, panel work, and conduit entry points where a clean finish matters. The Quick Change arbor system lets you swap cutter heads in seconds without tools — a real time-saver when you’re working through multiple hole sizes on the same job. A built-in flange stop prevents over-drilling and protects the workpiece surface, while the replaceable cobalt-steel pilot drill features a split-point tip that bites immediately and prevents walking on smooth or painted metal surfaces. Requires a minimum 3/8 in chuck, compatible with standard corded and cordless drills.
