Product Description

The DAYTON LAMINA HJB 87 325 M2 is a solid mold die blank punch designed for precision blanking and piercing operations in progressive die tooling. Built from M2 grade high-speed steel, this punch delivers a hardness rating of 60-63 HRC, making it well suited for high-volume stamping applications where wear resistance is critical. It features a ball lock retention system for secure seating in the punch holder and a shank diameter of 1 inch with an overall length of 3.25 inches. The minimum machinable length is 0.5 inches, and the pin extension length is 0.0625 inches. This punch is part of the Jektole HJB series and is sold as a single unit.

This blank punch is intended for use in mold and die stamping applications, including progressive die sets used in sheet metal fabrication shops, tool and die facilities, and metal stamping production environments. The ball lock style retention makes it compatible with standard ball lock punch retainers. It is installed and serviced by tool and die makers or press room technicians working with blanking, piercing, and forming die assemblies.
