Inch Regular Punches XNM Coating

This inch regular punch with an XNM coating is used in injection and die-cut tooling where repeatable piercing and punching performance is required across production runs. The coating is suited for applications that experience sliding wear at the punch tip and shank, helping maintain stable cutting edges and surface durability.

• Automotive and industrial connector stampings: Select among available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) to match hole geometry needs while using the inch punch format for straightforward integration into standard punch assemblies.
• Electronics enclosures and bracket blanking: Use the defined shank diameter range (12–125 in) and the coded point length options (standard and alternate ranges) to align with your die clearance and stripping requirements.
• General manufacturing sheet/laminate punching: The variant supports efficient changeovers in tooling because it follows standardized, coded sizing conventions for quick selection and replacement.

The provided specifications specify an XNM coating system for this punch variant, optimized for stable wear behavior at the working surfaces. However, the input data does not include the underlying steel grade, hardening route, or measured hardness (HRC), so those details cannot be stated reliably.

• Coating function: XNM is intended to improve punch surface durability and reduce wear during repeated punching cycles.
• Wear vs. toughness trade-off: Coatings typically enhance surface resistance while relying on the base steel for toughness; choosing the correct tip geometry helps manage localized stress at the point.
• Heat treatment: Not specified in the provided data; request steel and heat-treatment documentation if hardness verification is required for your process.

Select dimensions by matching your punch point geometry and shank fit to the die setup, starting with the required tip shape and then confirming the shank and length ranges. This series supports tip shapes H, J, K, L, N, O, R, V, X, Y, Z and a shank diameter D (in) = 12 ~ 125.

• Point length (B & L) selection: Use the Standard [S] Point Length coded inch range 150 ~ 250 or choose alternates such as 150–400 / 150–500 / 150–600 / 175–600 (Alternate [B]), 175–600 / 200–700 (Alternate [C]), 200–600 / 200–700 / 225–700 (Alternate [D]), and 225–700 / 250–700 (Alternate [E]).
• Profile dimensions: Confirm P = 0.042 ~ 0.625 in, W = 0.062 ~ 0.312 in, and R = 0.007 ~ 0.007 in to ensure the tip matches your cavity/core and cutting edge requirements.
• Tolerance/fit: No tolerance values are provided in the input; validate fit with your punch guide/bushing clearance and die opening tolerances using your supplier’s drawings.
