Dayton Lamina Hjb 87 500 M2 Solid Mold Die Blank Punch M2 Hss

Product Description

The DAYTON LAMINA HJB 87 500 M2 is a solid mold die blank punch designed for precision stamping and die-making operations. Built from M2 grade high-speed steel and hardened to 60-63 HRC, this punch delivers consistent performance under high-cycle tooling conditions. The ball lock retention system secures the punch firmly within the die set, minimizing movement during operation. With a 0.625-inch shank diameter and a 5-inch overall length, it fits standard ball lock punch holders used in progressive and compound die assemblies. Tool and die makers, mold makers, and precision machining shops are the primary users of this component.

This blank punch is part of the Jektole HJB Series from DAYTON LAMINA, a line engineered for solid blank configurations that require finish machining to final profile. It is suited for use in metal stamping dies, mold tooling, and custom punch fabrication in both job shop and production environments. The blank form allows the end user to machine the working end to a custom geometry, making it a versatile starting point for specialized tooling applications.

Key Features

• Ball lock shank design for secure, repeatable positioning in compatible punch holders
• 0.625-inch shank diameter with 5-inch overall length suits standard die set configurations
• Blank profile with 0.5-inch minimum machinable length allows custom tip geometry
• Part of the Jektole HJB Series, designed for solid mold and die blank applications

Compatibility

Designed as an OEM-style replacement and standard tooling component for ball lock punch holder systems used in metal stamping dies and mold die sets requiring a 0.625-inch shank diameter solid blank punch.

Installation Notes

Installation and machining of this punch should be performed by qualified tool and die makers or precision machinists. Ensure all press equipment is fully de-energized and locked out before removing or installing die components. The blank working end must be finish-machined to final profile before placing the punch into service. Verify ball lock engagement and shank seating before running the die under load.
