Straight Regular Punches Inch XNM Coating

These straight regular punches are used in inch-size press tooling where the punch axis must remain stable through repeated forming cycles. They suit applications such as automotive or appliance bracket punching, where accurate hole location and consistent cut quality depend on reliable punch guidance in the die set.

• Press tool die & punch assemblies: The straight regular geometry supports alignment in the press operation, helping maintain predictable penetration across cycles.
• Repetitive sheet-metal forming: The XNM coating is selected to improve wear behavior under cyclic load conditions, supporting longer intervals between surface-related maintenance.
• General manufacturing punching: The inch format simplifies procurement and substitution for standardized tooling builds.

Because the product is a standardized Dayton LAMINA part number and is offered in defined inch dimensions, it is well matched for tooling shops that need dependable fit-to-spec selection.

The provided specifications describe the straight regular punch configuration and XNM coating, but no underlying steel grade or measurable hardness (HRC) is included in the input data. Therefore, heat-treatment parameters (e.g., quenched & tempered, nitriding) and exact toughness-versus-wear trade-offs cannot be stated from the available information.

What can be confirmed from the dataset is that the XNM coating is intended to enhance performance in repetitive forming by improving wear and oxidation resistance under cyclic load conditions. This coating selection typically targets reduced surface degradation and more stable tooling behavior when punch faces experience repeated contact and sliding.

• Coating focus: improved wear/oxidation resistance in continuous press use.
• Limitations: no steel grade equivalence (e.g., SKD61/H13) or HRC value is provided for certification-level material comparison.

To select the correct punch, match the fixed length (L) and fixed P dimension to your press tool’s die and punch layout. From the provided ranges, L is available from 150 to 625 in, and P is available from 0.125 to 0.375 in.

• Length (L) matching: Choose L so the punch working length supports full stroke engagement without bottoming or insufficient protrusion in the tool holder.
• P dimension matching: Use the specified P value to align with the die-side geometry and the guidance/interface requirements for the press assembly.
• Fit & tolerances: Because no tolerance data is provided in the dataset, confirm allowable clearances and fit rules with your tooling standard before final selection.

These dimensions are fixed within each ordering configuration (i.e., you select within the stated L and P ranges rather than adjusting them during installation).
