Dayton Lamina Hjb 37 425 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 37 425 M2 is a solid mold die blank punch designed for precision stamping and die-making applications. Built from M2 grade high-speed steel and hardened to 60-63 HRC, this punch delivers consistent performance under high-cycle conditions. The ball lock retention system secures the punch in the holder without additional fasteners, reducing changeover time in production tooling setups. With a 3/8-inch shank diameter and an overall length of 4.25 inches, this blank punch is sized for standard mold and die assemblies. It is part of the Jektole (HJB) series and is intended for use by toolmakers, die setters, and precision machining professionals.

This punch is suited for use in stamping dies, mold tooling, and progressive die applications in both job shop and production manufacturing environments. The blank punch configuration allows the user to machine the tip to a custom profile, making it a flexible solution when standard geometry punches do not meet the required form. A minimum machinable length of 0.5 inches provides adequate material for custom tip profiling. The pin extension length of 0.0625 inches is compatible with ball lock punch retainers used in standard tooling plates.

Installation Notes

Installation is performed by toolmakers or die setters during tool build or punch replacement procedures. Ensure the tooling plate and retainer are free of chips and debris before seating the punch. Verify ball lock engagement before operating the press. Do not modify the shank diameter or ball lock groove, as dimensional changes will compromise retention and may result in punch ejection during cycling.
