Regular Punches Metric XCN Coating

This metric punch set is used in industrial die tooling for blanking, piercing, and form-cut steps, especially where wear at the punch face and flank reduces tool life. The XCN coating is suited for long-running production because it helps maintain surface durability during repeated cycles and controlled lubrication conditions.

• Progressive automotive connector and terminal tooling: punches with the selected tip shape (H/J/K/L/N/O/R/V/X/Y/Z) can be matched to feature geometry, helping keep dimensional stability as abrasive contacts accumulate.
• Electrical parts stamping and brackets: metric shank diameters in the 4–32 mm range support stable alignment in die blocks, reducing vibration-related wear in high cadence operations.
• General metalworking die and punch stations: choosing the appropriate point length band (e.g., 8–13 mm, 13–19 mm, 19–25 mm) supports proper engagement depth for consistent cutting performance.

These standard punches are offered in M2 or PS materials. M2 is a high-speed steel grade commonly selected for a balance of hardness and wear resistance in cutting and punching service; however, increased hardness can reduce toughness if severely shocked or overloaded. PS is typically chosen when the application prioritizes wear performance with practical toughness for stable forming in tooling environments.

Regardless of grade, the key performance driver for this variant is the XCN coating, which provides an additional wear-protective surface layer to improve punch life under repetitive sliding and abrasive contact. Heat treatment is typically provided as a hardened cutting-tool condition (commonly quenched and tempered for steels), so the working hardness supports abrasion resistance while maintaining controlled toughness for punching impacts.

Select a punch geometry by matching the required shank fit, point/working length, and tip shape to the die design and cutting gap. The shank diameter D is available from 4–32 mm; choose the D size that corresponds to the guide/bushing and die block hole diameter for stable positioning.

• Point length (L1): choose the band that matches the needed engagement depth: 8–13, 13–19, 19–25, or 25–30 mm.
• Total length (L): available ranges include 40–100, 50–100, 56–100, and 63–100 mm, allowing clearance to mounting height and stripper/die set stack-up.
• Tip profile parameters: pick the required tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and confirm feature dimensions such as P (0.8–10 mm), W (1.3–10 mm), and R (0.2 mm).

For best results, design tolerances around the mounting fit (shank-to-block) to avoid side loading; ensure the point length provides full working contact without bottoming in the die cavity.
