Double-Stepped Shoulder Punches for Heavy Load RW Coating

This is a two-stage punch for punching high tensile strength and thick plates, with improved coating adhesion by using a combination of Al-Cr coating, which has higher heat resistance and durability than conventional TiCN, and WPCⓇ treatment. Please use this when the required cutting edge length for the punch guide cannot be secured with the set cutting edge diameter.
