FROST Sheet Metal Cutter/Hole Punch 40MM Diameter Round

Available in metric sizes, these non-rotating hole cutters are an effective way of punching holes in sheet metal. Heat-treated for a long keen cutting life providing burr-free accuracy time after time. A small pilot hole is drilled allowing a connecting bolt to join the punch on one side and the die on the other side of the material. Pressure is then applied by tightening the bolt and thus the hole is literally punched out. A hexagon key is required to operate this tool, which can be purchased separately.
