Product Description

The EAGLE CUTTING TOOL TFZ-25178-ET is a cobalt hole cutter designed for cutting precise holes in sheet metal, HVAC ductwork, electrical enclosures, and similar trade applications. Built with a cobalt steel construction, this cutter delivers superior hardness and heat resistance compared to standard high-speed steel tools. The cutting diameter is 2-7/16 inches with a 1-inch depth of cut, making it suitable for producing clean, accurate penetrations through mild steel, stainless steel, and other ferrous materials. Tradespeople working in HVAC, plumbing, and electrical fields rely on this type of cutter for fast, repeatable hole production in demanding jobsite conditions.

This cutter is suited for residential and light commercial applications where precise hole sizing is required. Common uses include cutting duct openings, pipe penetrations, and electrical box knockouts. The universal impeller design allows the cutter to be driven by standard drill motors and compatible arbors, making it versatile across typical trade setups. HVAC technicians and sheet metal workers are the primary installers of this tool in both new construction and retrofit scenarios.
