This tool's unique swiveling head doubles it's function. Turned one way, the tool produces a neat flanged edge in sheet metal, just the right depth for welding two pieces together. Turn the head 180 degrees, and the tool becomes a hole punch, producing 3/16in. diameter holes perfect for easy riveting or plug welding. The handles are coated with non-slip rubber for a sure grip and are spring loaded to return to an open position. The handles are also 8in. long for great leverage. Works easily on metal up to 18 gauge. Made in Denmark.
