Extended Range Punches Metric XNAD Coating

This extended-range punch supports metal stamping and blanking operations in progressive and transfer dies where tool access is limited. The longer reach (L = 63–100 mm) helps maintain alignment and consistent punching at stations with tighter packaging, while the fixed point length (L1 = 25–30 mm) supports controlled penetration and product stability.

• Automotive bracket and connector housings: Use when thicker strip stacks and deeper die locations require extended straight-line punching to reduce deflection-related variation.
• Appliance and HVAC stamping: Metric shank diameters (D = 40–63 mm) provide stiffness for repeated cycles, helping maintain surface durability under punching loads.
• General forming of patterned or shaped blanks: Select from the available tip shapes (H, J, K, N, O, R, V, X, Y, Z) to match the required shearing/blanking edge geometry.

The XNAD coating is suited to these applications because it is engineered to reduce wear and support consistent forming across repeated cycles.

The provided data specifies an XNAD coating on extended-range punch tooling, but it does not include the underlying steel grade, heat-treatment condition, or hardness (HRC). Therefore, material heat treatment and hardness values cannot be stated from the supplied information.

• Coating function: The XNAD coating is designed to improve surface durability under punching loads, supporting steadier performance over repeated forming cycles.
• Wear vs. toughness trade-off: In punch steels, higher hardness generally increases wear resistance but can reduce impact toughness; coating systems are often used to extend wear life while maintaining the punch’s base-material integrity.
• Tip geometry influence: Available tip shapes (H, J, K, N, O, R, V, X, Y, Z) affect edge contact stress distribution, which interacts with coating performance.

If you share the steel grade/heat treatment from the drawing (or the punch’s technical datasheet), we can map it to an equivalent grade and provide an exact hardness and treatment description.

Select the extended-range punch by matching the tool reach, shank stiffness, and working point geometry to your die layout and cavity/core depths. Use L = 63–100 mm to span the die stack where the punch must reach the shear/blanking zone, and keep the point length L1 = 25–30 mm consistent with your required penetration profile.

• Shank diameter (D): Choose D in 40, 45, 50, 56, or 63 mm to ensure adequate stiffness and guide support inside the punch holder and corresponding die components.
• Tip shape: Select from H, J, K, N, O, R, V, X, Y, Z based on the blanking edge form and required shearing characteristics.
• Interface dimensions: Match the available P (20–39.95, 25–44.95, 30–49.95, 35–55.95, 40–62.95 mm) and W (8–39.95, 9–44.95, 10–49.95, 11–55.95, 12–62.95 mm) ranges to the die’s designed engagement area; verify R (0.2 up to 0.2–31.475 mm) for the required radius/edge relief.

Tolerance/fit values are not included in the provided specs, so confirm final fit by referencing your punch holder bore and die machining tolerances.
