Heat treated cutting edges with black anti-corrosive surface finish to prevent rusting.
All punches are sold singly without key, which should be ordered separately.
Thread the punch onto the hexagonal screw and then pass the hexagonal screw through the hole. Position the die on top of the die nut and then screw the die nut onto the projecting hexagonal screw until it touches the metal sheet. Use a hexagonal key to turn the hexagonal screw. The screw will pull the punch through the metal and a hole will result.
