Dayton Lamina Hjb 62 375 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 62 375 M2 is a solid mold die blank punch engineered for precision tooling applications in metal stamping and die work. Built from M2 grade high-speed steel and hardened to 60-63 HRC, this punch delivers consistent dimensional stability under repeated impact loads. The ball lock retention system secures the punch in the holder without set screws, reducing setup time during die changes. With a 1.0000-inch shank diameter and a 0.0625-inch pin extension length, this punch is ready for use as a blank or can be machined to a custom profile with a minimum machinable length of 0.5 inches. Weighing 0.25 pounds, it is part of the Jektole (HJB) Series from Dayton Lamina.

This punch is intended for use in progressive die sets, mold tooling, and blanking operations found in metal fabrication shops and tool and die environments. It is suited for applications requiring a close-tolerance, hardened punch that can be custom-ground to final profile. The ball lock design makes it a practical choice for high-change-frequency die stations where quick punch swaps are essential to production uptime.

Compatibility

Designed for use in ball lock punch retainer systems compatible with the Jektole (HJB) Series. Verify retainer bore diameter and ball lock pocket dimensions against your die set specifications before installation.

Installation Notes

Installation is performed by qualified tool and die technicians. Disengage and lock out all press energy before removing or installing any punch. Inspect the ball lock retainer and mating pocket for wear or debris before seating the punch. If grinding to a custom profile, use appropriate HSS grinding wheels and coolant to prevent heat buildup that could alter the hardness of the cutting face.
