Dayton Lamina Hjb 87 375 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 87 375 M2 is a solid mold die blank punch designed for precision stamping and die-making applications. Built from M2 grade high-speed steel with a hardness rating of 60-63 HRC, this punch delivers the wear resistance and edge retention required in demanding toolroom and production environments. The ball lock retention system secures the punch in the holder without the need for set screws, allowing for fast changeovers. This component is part of the Jektole (HJB) series and is installed by tool and die makers, machinists, and press operators working with progressive dies and mold tooling.

This blank punch is suited for use in stamping presses and die sets where a solid, unground punch body is required before secondary machining operations. The blank form allows shops to machine the working end to a custom profile, making it a versatile starting point for specialized punch geometries. It is commonly used in tool rooms handling medium to high-volume production die work.

Key Features

Compatibility

Designed for use in standard Jektole (HJB) series ball lock punch holder systems. Confirm holder bore diameter and retention style before installation.

Installation Notes

Installation should be performed by a qualified tool and die maker or machinist familiar with punch and die systems. Ensure the press is fully locked out and de-energized before removing or installing punches. The ball lock mechanism requires proper alignment with the holder groove to seat correctly - do not force the punch into the holder. Any secondary machining of the blank tip should be completed before press installation.
