Dayton Lamina Hjb 37 475 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 37 475 M2 is a solid mold die blank punch from the Jektole (HJB) series, engineered for precision tooling applications in stamping and die operations. Built from M2 grade high-speed steel, this punch delivers a hardness rating of 60-63 HRC, providing excellent wear resistance and edge retention under high-cycle conditions. The ball lock retention system ensures secure, repeatable seating in the punch holder. With a 4.75-inch overall length and a 1.0-inch shank diameter, this blank punch is suited for tool and die makers working in production stamping environments where dimensional accuracy and material durability are critical.

This blank punch is designed for use in mold and die tooling applications, including blanking, piercing, and related metal forming operations. The Jektole (HJB) series configuration is widely used in progressive die setups and solid mold die assemblies found in industrial production environments. Installation and tool changes are performed by qualified tool and die makers or precision machining professionals. The ball lock style allows for efficient punch changes without complete die disassembly, reducing downtime during production runs.

Installation Notes

Installation and removal of this punch should be performed by a qualified tool and die maker with the die set fully de-energized and press locked out per applicable machine safety standards. Verify punch holder bore diameter and ball lock mechanism condition before seating the punch. Do not force-fit the punch into an incompatible holder, as this can compromise dimensional tolerances and tooling integrity. Always confirm machinable length requirements before machining the working end to final form.
