Metric Regular Punches XCD Coating

These metric regular punches with an XCD coating are used in stamping and punching stations where the clearance between tooling components is limited. In close-space tool layouts (e.g., fine blanking-type layouts and compact progressive die stations), the punch profile can be specified for tight geometry while maintaining stable material removal.

• Automotive and appliance stampings: select the appropriate tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and point length range to match strip thickness and expected stroke count; the XCD layer supports lower friction and improved abrasion resistance.
• Electronics and thin-gauge part punching: use smaller shank diameters (D = 4–32 mm) and the correct P (0.8–10 mm) and W (1.3–10 mm) values to achieve consistent hole formation in thin materials.
• High-mix production: choose the body steel (M2 or PS) to align with wear vs. toughness needs, helping maintain consistent punching performance across varying part geometries.

Punch bodies are available in M2 or PS hardened steel to support stable wear performance in punching service. The provided information specifies that the bodies are in a hardened state for consistent abrasion resistance; the XCD coating further reduces friction at the cutting/contact interface.

• M2 steel: typically selected when higher wear resistance and longer cutting life are prioritized for abrasive or repetitive punching.
• PS steel: typically selected where a balanced performance is needed for punch toughness and predictable forming behavior across production runs.

As with any hardened punch steel, increasing wear resistance can trade off toughness. Selecting between M2 and PS is therefore driven by your expected cutting load, tool life targets, and whether the process is dominated by abrasion or by impact/deflection.

To select the correct punch, start by matching the shank diameter D = 4–32 mm to the tooling bushing/guide bore in your press or die set. Next, choose the length L (40–100 mm) in the range that provides full engagement without bottoming out, considering your holder stack height and clearance.

• Point engagement: select L1 (8–30 mm) based on the required penetration depth into the workpiece and the die clearance.
• Cutting profile dimensions: set the tip geometry using the available P = 0.8–10 mm, W = 1.3–10 mm, and R = 0.2–0.2 mm ranges to achieve the desired hole size and edge condition.
• Tooling compatibility: confirm the selected tip shape (H, J, K, L, N, O, R, V, X, Y, Z) matches your close-space clearance constraints and the mating die opening.

Because these parameters are specified as variable ranges rather than fixed values, ensure the chosen variant aligns exactly with the cavity/core opening and your press tolerance strategy.
