Dayton Lamina Hpb 50 450 M2 Solid Die Blank Punch

Product Description

The DAYTON LAMINA HPB 50 450 M2 is a solid mold die blank punch engineered for precision stamping and die-making applications. Built from M2 grade high-speed steel, it delivers consistent performance under the high-cycle demands of progressive and compound die operations. The ball lock retention system provides secure, repeatable positioning in the die set. With a hardness rating of 60-63 HRC, this punch resists wear and maintains dimensional integrity through extended production runs. The Regular (HPB) Series design follows established industry conventions, making it a straightforward drop-in format for standard tooling setups. Toolmakers, die makers, and precision machinists are the primary installers.

This blank punch is suited for use in mold and die stamping operations where a 0.25 inch shank diameter and ball lock style are required. The 4.5 inch overall length accommodates standard die shoe clearance depths typical of medium-duty press tooling. It is appropriate for both prototype and production tooling environments in shops working with sheet metal, light-gauge ferrous materials, and similar stock. Its solid construction means no inserted tips or brazed sections to fail under load.

Key Features

• M2 grade high-speed steel construction for high wear resistance and toughness
• 60-63 HRC hardness for extended service life in high-cycle stamping
• Ball lock retention system ensures repeatable, positive punch registration
• 0.25 inch shank diameter fits standard Regular (HPB) Series die components
• 4.5 inch overall length suits medium-depth die shoe configurations
• Solid one-piece body with no brazed or inserted sections

Compatibility

Designed as an OEM-style replacement or direct-fit component for Regular (HPB) Series die sets requiring a 0.25 inch shank ball lock blank punch.

Installation Notes

Installation of die punches should be performed by qualified toolmakers or die makers familiar with press tooling safety practices. De-energize and lock out the press before servicing any die components. Ensure the punch shank and ball lock pocket are clean and free of debris before seating the punch to maintain proper alignment and avoid premature wear. Follow shop-specific die maintenance procedures and applicable OSHA machine guarding requirements when working in or around die sets.
