When overlapping two pieces of sheet metal, you must "jog" the edge of one sheet so that they will join together seamlessly - and that's just what this tool does. The jogging die places a nice 1/2" jogging flange on the edge of sheet metal up to 16ga. While the other end of the die contains a hole punch that will make a clean 3/16" hole. This tool is a real time-saver if you do a lot of sheet metal work.
