Dayton Lamina Hjb 37 300 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 37 300 M2 is a solid mold die blank punch from the Jektole (HJB) series, designed for use in progressive die stamping and mold tooling applications. Built from M2 grade high-speed steel, this punch delivers hardness in the 60-63 HRC range, making it suitable for high-wear, high-volume punching operations. The ball lock retention system provides secure, repeatable seating in the die set. With a 3/8-inch shank diameter and 3 inches overall length, it is a standard-format blank punch ready for secondary machining to final profile by the toolmaker or die shop technician.

This blank punch is intended for use in progressive die tooling, stamping dies, and mold components where a solid, unground punch body is required prior to custom finishing. The Jektole (HJB) series is a widely recognized format in precision die work, commonly specified by tool and die makers in metalworking shops. The ball lock design allows fast changeout in die sets equipped with compatible retainer systems, reducing downtime during die maintenance or punch replacement cycles.

Installation Notes

Installation should be performed by a qualified tool and die maker or machinist familiar with progressive die components.

Verify retainer bore dimensions and ball lock seat condition before seating the punch. Secondary machining to final punch profile should be completed before placing the punch into active service.
