Dayton Lamina Kpb 50 350 Solid Mold Die Blank Punch

Product Description

The DAYTON LAMINA KPB 50 350 is a solid mold die blank punch engineered for use in progressive die and stamping tooling applications. It is manufactured from A2 grade tool steel, providing the hardness and wear resistance required for repetitive blanking operations. The punch features a basic head profile with a 0.625 inch head diameter, a 0.5 inch shank diameter, and a 3.1875 inch head height. Overall length is 3.5 inches. This punch is installed by tool and die makers or precision machining professionals building or maintaining stamping and forming die sets.

This blank punch is suited for use in solid mold die assemblies where consistent, repeatable blanking of sheet metal or similar workpiece materials is required. The Regular KPB Series designation identifies its head geometry and mounting configuration, making it appropriate for die plates designed around the KPB standard. Typical applications include production stamping dies in light manufacturing and metalworking shops where dimensional precision and tool longevity are priorities.

Key Features

• A2 grade tool steel construction for high hardness and resistance to wear in cyclic blanking operations
• Basic head profile in the Regular KPB Series for straightforward die plate integration
• 0.625 inch head diameter with 0.5 inch shank diameter for precise punch-to-die alignment
• 3.5 inch overall length accommodates standard die set stack heights
• Solid construction with no internal features, maximizing cross-sectional strength at the shank

Compatibility

Designed as an OEM-style replacement or new-build component for progressive die and stamping tooling assemblies requiring a KPB Series basic head blank punch with a 0.625 inch head diameter and 0.5 inch shank diameter.

Installation Notes

Installation is performed by qualified tool and die makers using precision press-fit or retained mounting methods appropriate to the die plate design. Power down and lock out all press equipment before servicing or replacing punch components. Verify punch-to-die clearance and alignment against die plate specifications before resuming production. Do not modify the shank or head geometry in the field without engineering review, as alterations may compromise tool integrity and die alignment.
