Dayton Lamina Hjb 87 450 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 87 450 M2 is a solid mold die blank punch designed for use in progressive die tooling and precision stamping operations. Built from M2 grade high-speed steel (HSS), this punch delivers hardness in the 60-63 HRC range, making it well-suited for demanding cutting and forming applications. It features a 7/8 inch (0.875 inch) shank diameter with a ball lock retention style, which provides secure, repeatable seating in the die set. The 4.5 inch overall length (OAL) accommodates standard die shoe configurations. Tool and die makers and precision machining professionals are the primary installers of this component.

This blank punch is part of the Jektole (HJB) series from Dayton Lamina, a line engineered for progressive and compound die applications across metal stamping operations. The solid blank configuration allows the end user to machine the punch face to the required profile, making it a flexible stock item for shops that need custom punch geometries without lead time for custom ground tooling. It is appropriate for use in both prototype and production tooling setups where M2 HSS hardness and dimensional consistency are required.

• 7/8 inch shank diameter with 0.625 inch minimum machinable length for custom face profiling
• 4.5 inch overall length suits standard die shoe and punch plate configurations
• Solid blank design allows custom grinding to required punch geometry
• Part of the Jektole (HJB) series, a widely stocked progressive die tooling line

Compatibility

Designed as an OEM-style replacement and stock blank punch for use in progressive die sets and compound die tooling that accept ball lock style punches with a 7/8 inch shank diameter. Verify punch holder and retainer specifications before installation.

Installation Notes

Installation is performed by tool and die makers or precision machinists in a die shop or toolroom setting. Before servicing or changing punches in a press, lock out and tag out all energy sources per OSHA LOTO procedures. Secure the ball lock engagement fully before press operation and verify punch alignment with the die button. Any custom grinding of the punch face should be completed before installation and must maintain the required hardness and geometry tolerances for the application.
