Inch Regular Punches XNAP Coating

In injection mold tooling, inch regular punches with an XNAP coating are typically used in tool/die station inserts and secondary forming steps where repeatable piercing and material shearing are required. They are well suited for automotive connector and terminal tooling, helping maintain consistent cutting edge behavior across large production runs while supporting reliable part-to-part identification.

• Automotive connector molds: Use the standardized point length coding to match downstream knock-out, stripper, or forming alignment requirements.
• Packaging and electrical housings: The XNAP-coated punch face supports stable wear protection during repeated punching cycles in high-cycle operations.
• General production tool assemblies: Select the tip shape option (X, R, K, O, H, L, J, N, V, Y, Z) to optimize contact geometry for the specific workpiece and process conditions.

The DAYTON Lamina standardized part numbering structure reduces specification drift between tool builds, simplifying setup verification and interchangeability across stations.

The provided series information specifies the XNAP coating and dimensional/tip code options, but it does not list a specific steel grade or hardness value. Therefore, this page should treat the steel and heat treatment as application-dependent per the supplier’s punch material selection.

From a materials perspective, the key performance attribute here is the XNAP coating, chosen to enhance wear resistance during repeated punching cycles. In practice, improved surface durability helps stabilize edge condition, which supports consistent forming/punching force and reduces variance over time.

• Coating-first differentiation: Focus selection on XNAP for wear protection when cycling is the dominant failure mode.
• Steel/heat treatment: Confirm the exact base material, quench/temper or other heat treatment state, and target hardness (HRC) for your die block and workpiece combination.

If multiple base steels are offered for this series, compare them by toughness vs. wear trade-offs after heat treatment, using your expected shock loading and cutting speed as the primary inputs.

Correct punch sizing starts with matching shank diameter (D) and point length codes to the receiving plate/tooling geometry. For this inch regular punch series, D is specified in the range 12 ~ 250 (in), and point length codes cover 150 ~ 250 for the standard [S] option. Alternate point length ranges expand up to 150 ~ 400, 150 ~ 500, 150 ~ 600, 175 ~ 600, 200 ~ 700, 225 ~ 700, and 250 ~ 700, depending on the [B]/[C]/[D]/[E] coding family.

• Match cavity/core interface: Use the coded point length to ensure the punch protrusion and working length align with the cavity/core or sub-plate opening depth.
• Tolerance/fit: Ensure D and any guided features in your punch holder maintain the intended clearance/press fit; verify dimensional and alignment requirements with your tool supplier drawings.
• Geometry selection: Choose the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to control penetration profile without changing base dimensions.

Track the coding-based dimensions (standard vs alternate point length options) as they are effectively configurable for different tool heights and contact depths.
