Inch Heavy-Duty Ball Lock Ejector Punches X-Shape Point

These heavy-duty ball lock ejector punches are used in die sets and injection-related tooling where a secure mechanical lock and repeatable ejection strokes are required. The X-shape point supports stable seating in the punch assembly, helping maintain alignment under repeated press or mold actuation.

• Automotive and industrial connector housings: In multi-cavity forming or trimming operations, the ball lock tip improves retention in the die set, reducing punch drift and supporting consistent ejection/strip-out cycle control.
• Appliance and consumer component dies: When high wear and frequent part changeovers stress ejector components, the heavy-duty inch format and secure retention help maintain dimensional stability over production runs.
• High-cycle inserts and guide-assisted systems: For applications using guide elements and controlled punch travel, the X-shaped point geometry helps ensure repeatable engagement with the mating ball-lock features.

Choose this variant for its secure ball-lock retention behavior and the X-shape point suited to robust die set integration.

This series is offered in M2 or PS4, both selected for wear resistance in ejector punch service. While exact heat-treat targets are not listed in the provided data, the intended performance is typically achieved by hardening and tempering followed by finishing to size for stable fit in punch assemblies.

• M2 steel option: Commonly selected for higher red-hardness and abrasion wear performance in demanding, high-cycle tooling.
• PS4 steel option: Often chosen as a wear-focused alternative for ejector components where toughness and surface durability balance is important.

Hardness (HRC) and the specific heat-treatment state (e.g., quenched & tempered, nitrided) are not provided in the input data; however, engineers should confirm hardness upon receipt because final fit and wear behavior depend on the as-supplied condition. In general, increasing wear resistance can reduce impact toughness—coordinate with cycle load, misalignment risk, and lubrication strategy.

Select the ejector punch by matching the shank diameter D and the required point length to the mating bore, guide, and the ball-lock retention feature in your punch assembly. For this series, D (shank dia.) is 37 ~ 125 (in), so choose the smallest D that satisfies load transfer and avoids excessive clearance in the die set.

• Tip shape: This variant uses the X-shape point. Confirm the tip shape code (X) matches your die set geometry for proper engagement and retention.
• Point length (coded inch): Standard length options are 250 ~ 500, 250 ~ 600, 275 ~ 600, and 300 ~ 600. Also verify which length set is applicable to your required B/C/D point length model.
• Over-stroke control: Use P (0.062 ~ 1), W (0.062 ~ 0.5), and R (0.007 ~ 0.007) dimensions to check fit/clearance at the mating interface.

Tolerance and fit details are not provided; therefore, treat the published dimension ranges as design baselines and validate clearance against the punch pocket/guide drawings from your die builder or assembly standard.
