Ball Lock Ejector Punches Heavy Duty Inch X-Shaped Tip

Ball lock ejector punches are used inside progressive and high-load die sets where consistent part release is critical over long press runs. The ball-lock style helps maintain secure positioning in the ejector system, reducing the risk of drift during repeated forming and blanking cycles.

• Precision blanking and forming: The controlled X-shaped tip geometry improves forming accuracy at the point of contact, supporting reliable material shearing and steady ejection of formed components.
• Progressive dies for electrical/connector housings: For multi-station operations, stable ejection reduces scrap caused by sticking parts between stations. The heavy-duty construction supports dependable performance under higher die-work loads.
• Thick-gauge or harder workpiece applications: Use this variant when you need robust wear resistance while retaining predictable ejection forces. Choose the specified inch shank diameters to match your press tool layout.

These design features make it well suited to tooling that prioritizes repeatable blanking quality and dependable part release.

This ejector punch series is offered in M2 or PS4 steel, both selected for die-work wear resistance. M2 is typically used when you want a balance of hardness and tool longevity for repeated ejection in progressive operations, while PS4 is selected for controlled performance in press tooling applications.

• M2 steel: Commonly selected for high wear service; suitable for heavy-duty die operations requiring stable point geometry and durable ejection.
• PS4 steel: An alternative steel option used to match tooling performance needs and manufacturing availability.

In practical mold/die production, the punches are machined to the specified shank diameter D (37 ~ 125 in) and point length codes, then finished to ensure consistent press-to-press fit. Final performance depends on the supplier’s heat treatment approach for the chosen grade, typically targeting a hardened condition to improve wear resistance; hardness/heat-treatment state may vary by selected material option.

Select the correct punch dimensions by matching the shank and point length coding to your ejector system and cavity/core geometry in the die. Start with the shank diameter D (37 ~ 125 in) to ensure proper seating in the ejector guide and alignment features.

• Choose point/tip shape: Confirm the required tip shape code (including X) to match the forming contact profile.
• Select standard point length & L (coded inch): Available ranges include 250 ~ 500, 250 ~ 600, 275 ~ 600, and 300 ~ 600 depending on the configuration.
• Verify length coding compatibility: The dataset lists coded-length variants for B & L, C, and D, each using the same set of inch-coded ranges (e.g., 250 ~ 500, 250 ~ 600, 275 ~ 600, 300 ~ 600).

Dimension features such as P (0.062 ~ 1 in) and W (0.062 ~ 0.5 in) should be checked against the die’s clearance and contact geometry to prevent interference or unstable ejection. Tolerances are not specified in the input data—confirm your fit requirements with the press/guiding system drawings.
