Regular Punches Metric XCDP Coating

These metric regular punches are used in precision die sets where reliable alignment and consistent forming force matter across high-volume production. The XCDP coating variant is particularly suited for long-run punching of strip or sheet profiles, helping resist abrasive wear and reducing tip degradation after repeated cycles.

• Automotive and appliance stamped parts: Use the fixed-point regular punch geometry with metric shank diameters in the 4–32 mm range to match common die shoe and guide layouts, maintaining stable punching position during continuous operation.
• General industrial stamping: Select appropriate tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) to suit the die cavity opening and part edge profile, while XCDP supports improved wear behavior under frequent punch repeats.
• Tooling programs requiring standardized procurement: The regular punch format supports easier maintenance and replacement planning in metric die work where the same punch family is reused across multiple production lots.

This punch series is offered in two steels: M2 and PS. M2 (tool steel, commonly aligned with the AISI M2 family) is selected when higher wear resistance and improved cutting edge stability are priorities for punching applications. PS is typically chosen where toughness and manufacturing convenience are balanced for routine production punching.

• XCDP coating: Adds surface protection to reduce wear during repeated punch cycles.
• Heat treatment (typical for punches): Both steel options are generally provided in a hardened, tempered state to achieve usable hardness while maintaining edge toughness for stable cutting.
• Hardness/toughness trade-off: M2 generally supports higher wear performance; PS may offer a more forgiving toughness profile depending on the supplied temper.

Exact hardness in HRC is not specified in the provided data, so hardness should be confirmed per batch or C of C documentation.

To select the correct punch size, start with the shank diameter D (4–32 mm) so the punch fits the corresponding die holder/punch guide bushing and maintains concentric alignment. Next, match the overall punch length L (40–100, 50–100, 56–100, 63–100 mm) to your die set height and stripper/guide stack-up, ensuring sufficient protrusion for the point while avoiding interference.

• Point length L1 (8–13, 13–19, 19–25, 25–30 mm): Choose based on penetration depth required to form the cavity opening cleanly.
• P and W dimensions (P: 0.8–10 mm; W: 1.3–10 mm): Use these to align with the specific tip geometry engagement features for the chosen tip shape.
• Tip shape: Select from H, J, K, L, N, O, R, V, X, Y, Z to match the die opening edge profile and desired burr/finish behavior.
• Tolerance/fit: Verify fit clearance in the punch guide for the selected D; tight fits can improve positional repeatability but may increase binding if stack tolerances accumulate.

These dimensions are provided as spec ranges; confirm the exact part drawing for your required combination of D, L, L1, P, W.
