Dayton Lamina Hjb 125 500 M2 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA HJB 125 500 M2 is a solid mold die blank punch from the Jektole (HJB) series, designed for use in precision metal stamping and die-making applications. Manufactured from M2 grade high-speed steel and hardened to 60-63 HRC, this punch delivers consistent performance under the repeated impact loads typical of blanking operations. With a 1-1/4-inch shank diameter and a 5-inch overall length, it is sized for heavy-duty tooling setups. The ball lock retention style provides secure, positive seating in compatible die sets. This component is installed by toolmakers and die maintenance technicians working in metal fabrication environments.

The HJB 125 500 M2 is suited for solid mold die tooling applications requiring a ground blank punch that can be finish-machined to a specific profile. Its 5-inch overall length accommodates a range of die stack heights, and the 0.5-inch minimum machinable length gives toolmakers adequate material for custom grinding. The ball lock design is common in high-production stamping dies where repeatable punch location and quick changeout matter. Fabrication shops, tool and die rooms, and precision metalworking facilities are the typical deployment environments for this punch.

Key Features

• M2 grade high-speed steel construction for wear resistance and toughness under impact
• Hardness rated at 60-63 HRC for extended tool life in high-cycle blanking operations
• Ball lock retention style for positive seating and repeatable punch positioning
• 5-inch overall length with 0.5-inch minimum machinable length for custom profile grinding
• 1-1/4-inch shank diameter with 0.0625-inch pin extension length
• Part of the Jektole (HJB) series, a standardized platform for mold die tooling

Compatibility

Designed as an OEM-style blank punch for use in ball lock die sets and tooling systems that accept a 1-1/4-inch shank diameter Jektole (HJB) series punch.

Installation Notes

Installation is performed by qualified toolmakers or die maintenance technicians. The press must be fully de-energized and locked out before any punch or die component is removed or installed. The blank punch is intended to be finish-ground to the required profile before use - do not run an unfinished blank punch in production tooling. Follow applicable shop safety standards and manufacturer tooling guidelines when grinding M2 high-speed steel.
