Close Space Punches
Close space punches are typically used to produce a hole in a stamped part when a multitude of punches are concentrated tightly in a limited area and limited space exist to fit the punches. Close space punches are also used in gaging and fixture tools to locate a part. Therefore exacting tolerances and concentricity are provided for superior alignment, better performance, longer runs, and less downtime. Close space punches are manufactured from the industry’s highest grade tool steels, high speed tool steels and stainless steels and are produced to comply with NAPMA, ISO 9001:2008, ISO 13485:2003 and alternative internationally accepted standards. All standard components are completely interchangeable with reputable competing brands.
