This sheet metal punch for stainless steel material splits the waste piece into 2 pieces. This prevents the waste piece from getting stuck on the tension screw and in the die. Max. sheet metal thickness: 2 mm with 11.1 mm tension screw/tension bolt. Properties: For manual and hydraulic operation. We recommend using a hand hydraulic device. Working with a ball bearing screw as a tension screw is possible, but not recommended. The high-alloy tool steel we have selected and the thermal treatment guarantee a long service life.
