Point Larger than Shank Ball Lock Punches Heavy Duty, Inch

This heavy-duty ball-lock punch variant is used in injection and stamping tooling where repeatable ejection and secure retention are critical, especially under high cycle loads. The larger point improves engagement with mating components, helping maintain stable ball-lock fit during frequent actuation.

• Automotive and appliance stamping dies: Suitable for progressive stamping operations that experience abrasive wear and misalignment risk, where the XNA coating helps reduce friction and wear at the point interface.
• High-load die sets and multi-station tooling: The ball-lock geometry supports consistent retention and reliable ejection, reducing the chance of point-side galling that can lead to sticking.
• Thick-gauge or wear-prone production runs: The inch heavy-duty construction is selected when robust ejection performance is required across demanding production cycles.

Choose the point shape (H, J, K, L, N, O, R, V, X, Y, Z) that matches your cavity/core contact profile to ensure consistent clearance and contact area.

The provided specifications for this product focus on geometry and coating rather than a named steel grade, so the material selection should be based on your tooling supplier’s corresponding punch steel family for DAYTON heavy-duty ball-lock punches. For this variant, the key functional surface feature is the XNA coating, which is intended to lower friction and mitigate point wear during ejection.

• XNA coating: Helps reduce wear and friction at the sliding/contact zone, improving stability in high-frequency production.
• Wear vs. toughness trade-off: In ball-lock punch systems, the point region typically benefits from a wear-resistant surface while the shank relies on bulk toughness to tolerate impact loads during cycling.

If you need heat treatment details (e.g., pre-hardened vs. quenched & tempered, nitrided), confirm with your internal standard or request the corresponding material/heat-treatment datasheet from Axiom Molds for series 250300512627.

Select dimensions by matching your mold/die cavity geometry and the required ejection contact profile. This product supports multiple tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) and must be chosen to match the mating feature on the part or stripper.

• Shank diameter D: Choose within 37 ~ 125 in range (per your series listing).
• P dimension: Select 0.376 ~ 1.251 in based on the point/step engagement geometry you need.
• W dimension: Select 0.062 ~ 1.083 in to match the localized contact width/land requirements.
• Length L (coded inch): Available ranges include 250 ~ 450 and 275 ~ 450; ensure the punch length supports correct guide reach and travel without bottoming.

For ball-lock retention, verify that your mating block pocket and ball seat dimensions align with the selected D and point geometry; follow your tooling’s clearance and fit practice to prevent binding while maintaining secure retention.
