Product Description

The GREENLEE 1745AV is a 13/16-inch chassis punch designed for cutting clean, precise holes in electrical enclosures, panels, and sheet metal. This knockout punch is used to create openings for conduit fittings, grommets, and other panel-mount components. It is built for use by licensed electricians and electrical contractors working on control panels, junction boxes, and distribution enclosures. At 0.25 pounds, the 1745AV is a compact, lightweight tool that fits standard Greenlee knockout punch driver sets. The finished hole diameter of 13/16 inch suits a range of small-diameter fittings and panel hardware commonly found in commercial and industrial electrical work.
