Dayton Lamina Hjb 62 450 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 62 450 M2 is a solid mold die blank punch designed for use in progressive die stamping and precision tooling applications. Manufactured from M2 grade high-speed steel, this punch delivers hardness in the 60-63 HRC range, making it well-suited for demanding blanking and forming operations. The ball lock retention style provides positive punch retention in the die set without the need for additional hardware. This is a professional-grade tooling component installed and serviced by tool and die makers, press room technicians, and precision machining specialists.

This punch belongs to the Jektole (HJB) Series from Dayton Lamina and is intended for use in mold and die tooling setups where a solid blank punch body is required before final machining to application-specific geometry. With a 0.625-inch pin extension length and a minimum machinable length of 0.5 inches, this blank punch provides adequate material for custom profiling. It is commonly used in high-volume metal stamping operations across automotive, appliance, and industrial manufacturing environments.

Compatibility

Designed as an OEM-style solid blank punch for use in progressive die and mold tooling assemblies that accept ball lock style punches with a 0.7-inch shank diameter.

Installation Notes

Installation and machining of this blank punch should be performed by a qualified tool and die maker or precision machinist. Disengage and lock out all press energy sources before removing or installing punch components in any die set. Final machining to profile must respect the minimum machinable length to maintain structural integrity of the punch. Follow applicable OSHA and shop safety standards when working with press tooling and grinding equipment.
