ABSTRACT OF THE DISCLOSURE An improved punch assembly tooling for turret punch presses is described. The tooling comprises removeable punch inserts which are connected to the striker assembly by a single retainer bolt located in a central bore running along the longitudinal axis of the punch assembly. This direct connection means of the components of the striker assembly improves tonnage transmission as impacts are not transmitted via springs, threads, pins or other intermediate links in impact path. Improvements in alignment and orientation are also provided as well as more reliable stripping. Inserts are simply removed from the front without having to remove entire punch assembly from turret bore. The tooling also provides significant improvements in general ease of operation, reduced cost for punch inserts, and improved reliability due to sealed construction allowing more effective lubrication. 18
