Point Larger than Shank Ball Lock Punches - Heavy Duty | XNA Coating

These heavy-duty ball lock punches are used in metric die work where the punch point must stay firmly positioned and return consistently over high cycle counts. The larger point relative to the shank improves punch-to-opening control, helping reduce misalignment during repeated forming operations.

• Automotive and industrial forming dies: Ideal for station inserts that rely on stable ball-lock retention; the XNA coating supports wear resistance at the point where sliding and contact are most severe.
• Appliance/equipment component dies: Suitable for die cavities that see frequent stop/start production and tool maintenance cycles, since the controlled point geometry helps maintain consistent locating and ejection.
• General heavy-duty punching and blanking: Works well with common ejector punch setups where reliable ball lock positioning is required to prevent retention drift.

This variant is specified with an XNA coating, selected to enhance wear resistance in the punch point region under production load. While the base steel grade and exact heat treatment/hardness are not provided in the supplied data, the coating is typically applied to reduce surface wear and help maintain point geometry during repeated cycling.

• Wear vs. toughness trade-off: Coatings improve sliding/contact life, but performance still depends on maintaining adequate punch-point edge integrity under load.
• Heat treatment state: Not specified for this product listing; treat as a coated punch intended for heavy-duty die service where surface durability is the key differentiator.

If you share the target load, cavity pressure, and required cycle life, Axiom Molds can recommend the most suitable substrate/heat-treatment pairing for your specific tooling conditions.

Select a configuration by matching the ball-lock punch dimensions to your die cavity/core interface and opening geometry. Use the provided D (shank dia.) options to align the punch body with your guide/retention bore: 13, 16, 20, 25, 32, 40 mm.

• Point length (L1): choose within 19 to 30 mm to ensure the point fully engages the die opening for reliable ball-lock retention.
• Total punch length (L): confirm L = 80 to 100 mm fits your die space and ejector train stroke requirements.
• Compatibility checks: verify the P dimension and W range (1.57 to 34.73 mm) against the mating features controlling seating and clearance. Also confirm the R (radius) selection (0.2 to 16/19/20/22/25/28 mm) aligns with the intended point-to-opening profile.

Tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and Jektole group (J6, J9, J12) should be chosen to match the specific ball-lock geometry of your existing die design.
