Close Space Punches - Metric (XNM Coating)

Close-space punches are used in injection-mold tooling mainly as secondary tooling elements for insert formation, ejector/stripper-linked operations, and fine-feature die stations where punch-to-hole clearance must remain controlled throughout production.

• Progressive and transfer die lines: The close-space geometry supports stable punch guidance in close-tolerance assemblies, helping reduce alignment drift over repeated strokes.
• Automotive and appliance part forming: When forming operations require consistent hole location and predictable material flow, the fixed shank reference with your selected P dimension improves repeatability in tight tooling stacks.
• High-cycle production runs: The XNM coating is suited for environments that demand better wear performance, extending usable punch life in abrasive or high-frequency die conditions.

Choose the metric variant for compatibility with standard tooling layouts, and select a shank diameter (D) that matches the guide and feed interfaces in your die set.

The provided data specifies the XNM coating applied to this close-space metric punch set, which is intended to enhance surface wear resistance for reliable production cycles. While the exact base steel grade and heat-treatment condition are not listed in the specifications provided, coating performance is typically leveraged to improve durability without changing the underlying dimensional reference of the punch.

• Wear resistance vs. toughness trade-off: In close-space guidance, maintaining low wear at the punch’s working surfaces helps preserve clearance and alignment; however, coating thickness and surface finish must be controlled to avoid changes in fit.
• Hardness (HRC): Not specified in the input data; verify with the manufacturer’s material certificate for the final HRC target after any pre-hardened or quenched-and-tempered processing.
• Manufacturing process: The punch is supplied with a defined close-space geometry and an XNM surface layer to support stable guidance under repeated load.

For any project requiring certified hardness and heat-treatment state, request the material report for this series code.

Select dimensions by matching the punch’s shank and close-space clearance requirements to the die assembly geometry. This series provides D (shank diameter) options of 02, 03, 04, 05, 06, 07, and a fixed L (length) range of 40–100 mm.

• Choose D first: Match the selected D to the guide/receiver bore and the close-space guidance interface so the punch remains centered and repeatable during cycling.
• Set working projection with L: Confirm that the selected L (40–100 mm) provides the required engagement depth without interfering with adjacent die blocks or stops.
• Verify clearance using P: The P dimension is variable from 0.8 to 6.01 mm. Use P to tune the close-space assembly clearance so alignment is maintained under repeated forming.

Because tolerance values are not included in the provided data, confirm fit and clearance tolerances with your die drawing requirements and request tolerance documentation for the selected D, L, and P combination.
