For professionals or demanding DIYers, this 35 mm Rothenberger steel punch is designed to precisely punch through steel sheets, V2A stainless steel, copper, and aluminum up to 4 mm thick—without deformation or burrs. Its 3-point punch design ensures a stable grip and consistent stamping, even in the most confined configurations: junction boxes, switch cabinets, control panels, sinks, or vehicle bodies. The metric tension bolt reinforces the assembly to withstand repeated use. A reliable tool, sold individually, that is essential where precision allows for no compromise.
