The Tork Craft Chassis Screw Sheet Metal Punch is a hand tool used to punch a hole in sheet metal. It is a very simple tool consisting of a punch, die and screw.
To set up the punch, first drill a pilot hole in a piece of sheet metal with a step drill, place the die over the draw pin before inserting the pin through the pilot hole. The punch is then threaded onto the tip of the draw pin and brought close to the sheet metal.
