A punch and die system is disclosed as comprising punch and die templets serving to positionally locate punch and die assemblies relative thereto solely adjacent the region at which punching of a workpiece occurs in combination with guide assemblies for positionally locating the punch and die templets one to the other. The punch and die assemblies are designed to utilize interchangeable punch guide and die members and in a preferred construction a punch element is removably attached to its associated driver and shaped to permit opposite ends thereof to be employed in the punching operation. One or more punch elements may be loosely attached to their associated drivers.
