Dayton Lamina Hjb 62 425 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 62 425 M2 is a solid mold die blank punch from the Jektole (HJB) series, designed for precision blanking and punching operations in mold and die tooling applications. Manufactured from M2 grade high-speed steel, the punch delivers a hardness rating of 60-63 HRC for reliable performance under high-stress, repetitive stamping cycles. It features a ball lock retention system for secure, repeatable mounting in the punch holder. The overall length is 4.25 inches, with a shank diameter of 3.0 inches. This tool is installed and serviced by tool and die makers, mold builders, and precision machining professionals.

This blank punch is suited for use in progressive die sets, mold and die tooling fixtures, and custom stamping operations where a machinable blank is required. The Jektole (HJB) series design allows the end user to machine the working end to a custom profile, making it appropriate for specialty punch geometries that are not available as finished catalog tooling. Typical applications include metal stamping, blanking, and forming operations in industrial manufacturing environments. The 0.5-inch minimum machinable length supports flexibility in custom tip profiling.

Installation Notes

Installation is performed by qualified tool and die makers or machining professionals in a controlled shop environment. Before removing or installing any punch, ensure the press is fully de-energized, locked out, and tagged out per applicable OSHA lockout/tagout procedures. The blank tip must be machined to the required profile before the punch is placed into service. Verify shank fit, ball lock engagement, and punch alignment within the die set before returning the tooling to production.
