Dayton Lamina Hjb 62 475 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 62 475 M2 is a solid mold die blank punch from the Jektole (HJB) series, engineered for precision blanking and die work in metal stamping and mold-making applications. Manufactured from M2 grade high-speed steel and heat-treated to a hardness of 60-63 HRC, this punch delivers consistent performance under high-impact cyclic loading. The ball lock retention system provides positive, repeatable seating in the punch holder without the need for set screws. With a 1.23-inch shank diameter and an overall length of 4.75 inches, this blank punch is sized for standard die set configurations used by toolmakers and die maintenance technicians.

This blank punch is designed for use in metal stamping dies, progressive dies, and mold and die fabrication environments. The Jektole (HJB) series is a recognized standard in the tool and die industry, commonly found in both production stamping shops and precision tool rooms. The unfinished blank profile allows machinists to grind the working end to a custom profile suited to the specific die application. Typical installers include tool and die makers, punch press maintenance technicians, and precision machining shops working with ferrous and non-ferrous sheet materials.

Installation Notes

Installation should be performed by a qualified tool and die maker or press maintenance technician. Ensure the press is locked out and all energy sources are isolated before removing or installing punches. Confirm the punch holder bore and ball lock pocket are clean and free of debris before seating the punch. Do not modify the shank diameter or ball lock geometry; machine only the working end to the required profile.
