Dayton Lamina Hjb 50 375 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 50 375 M2 is a solid mold die blank punch engineered for precision stamping and die work in tool-and-die and metal fabrication environments. Part of the Jektole (HJB) Series, this blank punch features a 0.5-inch shank diameter and a 3.75-inch overall length (OAL). Constructed from M2 grade high-speed steel and heat treated to 60-63 HRC, it delivers the hardness and wear resistance required for high-cycle punch press applications. The ball lock retention style ensures secure, repeatable positioning within the die set. Licensed tool-and-die makers and precision machinists are the primary installers of this component.

This blank punch is suited for use in mold and die applications where a machinable punch body is required. The 0.5-inch minimum machinable length and 0.0625-inch pin extension length allow the punch to be ground or profiled to a custom working geometry at the shop. It is appropriate for use in progressive dies, blanking dies, and similar tooling configurations common in both production stamping shops and prototype tooling environments. The Jektole (HJB) Series design is a recognized standard format in the die components industry.

Installation Notes

Installation is performed by licensed tool-and-die makers or qualified machinists. The punch body should be ground to the required working profile before installation using appropriate surface or cylindrical grinding equipment. Ensure the die set and punch holder are fully de-energized and the press is locked out and tagged out per OSHA lockout/tagout procedures before punch removal or installation. Verify ball lock pin engagement and punch seating before returning the die to service.
