Dayton Lamina Kpb 31 250 M2 Solid Die Blank Punch M2 Hss

Product Description

The DAYTON LAMINA KPB 31 250 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 the hardness and wear resistance required for demanding metal-forming operations. The punch features a basic head profile with a 7/16 inch head diameter, 5/16 inch shank diameter, and a 1/8 inch head height. Overall length is 2.5 inches. The KPB Regular series design is a direct fit for standard die sets and mold base tooling. Licensed toolmakers, die makers, and press room technicians are the primary installers of this component.

This blank punch is suited for use in progressive dies, compound dies, and mold die sets in both job shop and production stamping environments. The KPB series is a standard configuration used in light-to-medium duty blanking and punching operations where consistent dimensional accuracy is required. It is appropriate for low-to-moderate tonnage press applications where a solid, unretained blank punch style is specified by the die design.

Key Features

• M2 grade high speed steel construction for high hardness and abrasion resistance
• Basic head profile for compatibility with standard die set retainer configurations
• 7/16 inch head diameter with 5/16 inch shank diameter
• 1/8 inch head height for precise seating in die sets
• 2.5 inch overall length suitable for standard shut height tooling
• Solid one-piece construction with no mechanical joints or inserts

Compatibility

Designed as an OEM-style replacement or standard-stocked component for use in KPB Regular series die sets and mold base tooling configurations requiring a solid blank punch with a basic head style.

Installation Notes

Installation is performed by qualified toolmakers or die maintenance technicians. The die set and press must be fully de-energized and locked out before any tooling changeout or punch replacement. Punch fit and retention method should be verified against the die design drawing prior to assembly. Follow applicable OSHA machine guarding and ANSI B11 press safety standards during all tooling service operations.
