VALLCIA BEARING PUNCH 51mm (2")

Mechanical sheet metal perforators with unground bearing. Standard perforators can cut up to 2 mm into steel sheets and 1.2 mm into stainless steel sheets. The screws of the 55 series drillers are of very high strength 140 kg/mm2. Thanks to the bearing they include, the performance of the perforator increases by 200%. This means that it requires half the strength.
