XN DayTride Coated Point Larger than Shank Ball Lock Punches Heavy Duty, Metric

These metric ball lock punches are used in punch-and-die tooling where repeatable blanking or piercing depends on precise alignment and secure retention in the ejector or guide assembly.

• Automotive and general metal forming blanking: the larger-than-shank point helps guide the ball lock engagement during high-cycle stamping, supporting stable operation when the tool is repeatedly driven and withdrawn.
• Die piercing and slotting: the XN DayTride coating is intended to improve wear resistance at the punch working face, helping maintain consistent blanking performance over multiple production runs.
• Progressive or transfer die stations: fixed overall punch length options (L = 80–100 mm) make it easier to match station-specific layouts while preserving reliable positioning in the ball lock interface.

With a metric shank diameter range (D = 13, 16, 20, 25, 32, 40 mm), this variant is suited for dies requiring a robust ball lock retention under heavy-duty forming loads.

This product variant specifies an XN DayTride coating for heavy duty metric stamping applications. While the underlying base steel grade is not stated in the provided data, the coating is selected for its contribution to wear resistance at the working point where abrasive and adhesive wear occur.

• Wear vs. toughness trade-off: hard coated surfaces typically increase abrasion resistance, but punch performance still depends on sufficient core toughness to avoid chipping under impact loading.
• Heat treatment state: no explicit heat treatment condition (e.g., quenched & tempered, nitrided) or hardness value (HRC) is provided in the input data, so it cannot be confirmed from specifications.
• Coating-focused comparison: where alternatives use different surface treatments, the key differentiator here is the XN DayTride layer intended for longer service life in repetitive blanking/piercing.

For detailed hardness (HRC) and base grade selection, request the steel and heat treatment sheet tied to series code 250301837055.

Select the punch geometry by matching the die station requirements for shank fit, working-point engagement, and overall length clearance.

• Shank diameter (D): choose from 13, 16, 20, 25, 32, 40 mm to correspond to the ball-lock punch seat and guides in your ejector assembly.
• Point length (L1): set working projection using L1 = 19–30 mm to control penetration depth and material contact at the forming interface.
• Overall length (L): confirm tooling space and mounting stick-out using L = 80–100 mm.
• Tip shape: pick the required tip contour from H, J, K, L, N, O, R, V, X, Y, Z based on die wear behavior and desired shear/entry characteristics.

Also verify the specified intermediate dimensions against your assembly: P ranges from 13.1–32 mm (and corresponding higher ranges listed) and R from 0.2–16 mm (with additional maxima by configuration). Tolerance/fit values are not provided, so align these dimensions to your housing pocket and retention system drawings to ensure proper ball lock engagement.
