• for signal lamps, glands, buttons
• maximum sheet metal thickness up to 2 mm (at Rm<450MPa, e.g. type St3S)
• increased durability of punching elements and bolt/pin
• up to ø 38,5 mm waste is cut into two parts for easier removal, at larger diameters
waste is strongly deformed and therefore easy to remove
