Dayton Lamina Kpb 31 300 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA KPB 31 300 is a solid mold die blank punch designed for use in stamping and progressive die tooling applications. Manufactured from A2 grade tool steel, this punch delivers the hardness and wear resistance required for high-cycle metal forming operations. It features a basic head style with a 7/16-inch head diameter, a 5/16-inch shank diameter, and a 1/8-inch head height. The overall length is 3 inches. This is a KPB Regular Series blank punch, sold as a single unit, and is typically installed by tool and die makers or press room technicians maintaining production tooling.

This blank punch is suited for use in solid mold die sets found in metal stamping and fabrication environments, both in job shop and production manufacturing settings. The KPB series is a standard configuration widely used in progressive and compound die assemblies. Its blank punch geometry makes it appropriate for applications requiring clean, repeatable blanking strokes in sheet metal processing.
