SKH51 Material Die Punch Pins / Polished Punching Pins For Stamping Punch Mould
Die punch pins are essential accessories for stamping die operations. These replaceable mold consumables are mounted on stamping dies to perform continuous punching operations, separating or plastically deforming materials to produce finished or semi-finished products.
Available in various materials including SKD, SKH, and ASP, SKH punch pins are manufactured from specialized mold steel. Material differences result in varying appearances - tungsten steel pins appear darker while high-speed steel pins have a brighter finish.
