Dayton Lamina Hjb 100 375 M2 Ball Lock Die Blank Punch M2 Hss

Product Description

The DAYTON LAMINA HJB 100 375 M2 is a solid mold die blank punch designed for precision stamping and die-making applications. Built from M2 grade high-speed steel, this punch delivers a hardness rating of 60-63 HRC, making it well suited to high-wear tooling environments. The ball lock retention system provides positive punch seating in compatible die sets, reducing setup time and improving repeatability. With a 1.0000-inch shank diameter and a minimum machinable length of 0.5 inches, this blank punch gives tool and die makers a reliable starting point for custom ground profiles. It weighs approximately 0.4375 pounds.

This blank punch is used in tool and die shops, stamping operations, and moldmaking environments where a precision-ground, hardened punch blank is required before final form grinding. The Jektole (HJB) series is a recognized standard format in progressive die and mold die tooling. The part ships ready for secondary machining or direct installation depending on application requirements. It is appropriate for both prototype and production tooling contexts.

Installation Notes

Installation of die punches should be performed by qualified tool and die makers or press room technicians. Ensure the press and die set are fully de-energized and at rest before inserting or removing punch components. Verify ball lock retention engagement before returning the die to service. Follow applicable OSHA and ANSI B11 standards for press and die safety during setup and maintenance.
