Dayton Lamina Kpb 25 175 M2 Solid Die Blank Punch M2 Hss

Product Description

The DAYTON LAMINA KPB 25 175 M2 is a solid mold die blank punch manufactured from M2 grade high speed steel. It belongs to the Regular (KPB) series and features a basic head profile with a 0.375 inch head diameter, a 0.25 inch shank diameter, and a 0.125 inch head height. Overall length is 1.75 inches. This punch is designed for use in stamping and die applications where consistent dimensional accuracy and material toughness are required. Tool and die makers, mold builders, and press room technicians work with components like this during die assembly and punch replacement operations.

The KPB 25 175 M2 punch fits into solid mold die sets in both production stamping environments and prototype tooling setups. The basic head configuration suits standard retainer plate systems. Its compact shank diameter makes it appropriate for close-tolerance punch layouts in progressive, compound, or single-station die assemblies. M2 high speed steel provides the hardness and wear resistance needed for repeated blanking and piercing cycles on ferrous and non-ferrous stock materials.

Key Features

• M2 grade high speed steel construction for hardness and wear resistance under cyclic load
• Basic head profile compatible with standard punch retainer plates
• 0.375 inch head diameter with 0.25 inch shank diameter for compact punch layout spacing
• 1.75 inch overall length suits typical die set stack heights
• Solid construction with no internal cavities for consistent performance under press load
• Part of the Regular (KPB) series for straightforward sourcing and replacement

Compatibility

Designed as an OEM-style replacement or direct-fit component for solid mold die sets using standard basic head punch retainer systems within the Regular (KPB) series.

Installation Notes

Installation should be performed by a qualified tool and die maker or press room technician. The press must be de-energized and locked out before any die set disassembly or punch replacement. Verify retainer plate bore diameter and head seat depth match punch dimensions before pressing the component into position. Do not force or impact the punch head during seating, as this can affect dimensional alignment and punch face integrity.
