Dayton Lamina Hjb 125 450 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 125 450 M2 is a solid mold die blank punch from the Jektole (HJB) series, engineered for precision blanking and punching operations in mold and die applications. Built from M2 grade high-speed steel, this punch delivers a hardness rating of 60-63 HRC, providing excellent wear resistance under high-cycle conditions. The ball lock retention system ensures secure seating in the die set without the need for additional fasteners. With a 4.5-inch overall length and a 1.25-inch shank diameter, this punch is sized for demanding production tooling environments. Tool and die makers, machining shops, and stamping operations rely on components like this for repeatable, high-tolerance performance.

This blank punch is designed for use in solid mold die sets where the working end requires custom machining to a specific profile. The Jektole (HJB) series configuration makes it well suited for progressive die, stamping, and forming tooling. The blank profile allows in-house grinding or EDM to the required punch geometry, giving toolmakers flexibility across a wide range of part profiles. Typical applications include metal stamping dies in both light and heavy manufacturing environments where M2 high-speed steel is the specified material grade.

Installation Notes

Installation of die punches should be performed by qualified tool and die makers or machine shop personnel with experience in die set assembly. Ensure the press is fully locked out and de-energized before removing or installing any die components. The blank punch tip must be precision ground or EDM-machined to the required profile before production use. Verify ball lock seating and retention before cycling the press.
