Dayton Lamina Hjb 62 300 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 62 300 M2 is a solid mold die blank punch designed for use in stamping and die-making operations. Built from M2 grade high-speed steel, this punch delivers consistent hardness of 60-63 HRC across demanding production cycles. The ball lock retention system provides secure, repeatable positioning within the die set. With a 3-inch overall length and a 1-inch shank diameter, this punch is sized for medium-duty tooling applications. Die makers and tool and die technicians specify this part when building or maintaining progressive, compound, or transfer dies requiring a machinable blank punch body.

This blank punch is suited for precision die and mold tooling environments in both production shops and job shops. The Jektole HJB series is a recognized standard in blank punch tooling, used across stamping operations that require the punch to be machined to a custom profile by the toolmaker. The solid construction and M2 steel grade make it appropriate for applications involving mild steel, aluminum, and similar workpiece materials. It is typically installed in die sets used in metal fabrication, appliance manufacturing, and automotive component production.

Key Features

Installation Notes

Installation is performed by qualified tool and die technicians. Disengage and lock out all press energy before removing or installing any punch components. The blank punch body requires profile machining prior to use - verify final ground dimensions meet drawing tolerances before installation. Confirm ball lock pin engagement and punch retention before returning the die set to production.
