Ball Lock Ejector Punches Light Duty Inch X-Shaped Tip

Ball-lock ejector punches with an X-shaped tip are used in light-duty inch injection and press tooling where ejector guidance must remain stable during die opening and closing. Their ball-lock head provides reliable retention in the punch housing, helping prevent punch float and misalignment under frequent cycling.

• Die alignment and controlled ejection: In position-critical systems for small inserts or die components, the X-shaped tip geometry supports predictable entry and release at the cavity interface.
• Press tooling for locator-driven assemblies: The point-larger-than-shank locating concept improves stability of the ball-lock engagement while maintaining consistent ejection force transmission in light-duty applications.
• Modular tooling and quick die changes: Standardized inch-based shank diameters and coded lengths simplify engineering selection and compatibility checks across recurring die projects.

This variant is suited to these scenarios because it combines a retention-focused ball-lock design with an X-shaped tip that promotes repeatable die interaction using inch tooling dimensions.

The provided data specifies the geometric and inch sizing features of this light-duty ejector punch system, but it does not include the steel grade, heat-treatment condition, or hardness (HRC). Therefore, material hardness, wear resistance, and toughness trade-offs cannot be stated from the supplied specification.

• Tip shape and engagement behavior: The ball-lock retention and point-larger-than-shank design primarily influence stability and repeatability at the die interface.
• Heat treatment: No quench/temper, nitriding, or pre-hardened state is listed in the input parameters.
• Steel-grade comparison: Since no alternative materials or grades are provided, comparisons (e.g., SKD61 vs. H13, or M2 vs. equivalent) are not supported.

If you can share the actual punch material grade and hardness specification from the product datasheet, the material_html can be updated with accurate heat treatment and HRC-based guidance.

Select the ejector punch by matching the shank diameter D, coded length L, and tip/point dimensions to the punch housing and cavity/core interaction requirements.

• Shank diameter (D, in): Choose from 37 (0.3750), 50 (0.5000), 62 (0.6250), 75 (0.7500), 87 (0.8750), or 100 (1.0000).
• Length (L coded inch): Use L in the range 250 ～ 450, selecting the coded value that provides the required stick-out while maintaining proper guide engagement.
• Tip/geometry controls: Match P (in) to the available ranges (0.376～0.875, 0.501～1.25, 0.626～1.5, 0.751～1.5, 0.876～1.75, 1.001～1.75) and W (in) to 0.062～0.867. Select R (in) from 0.007～0.4375, 0.007～0.625, 0.007～0.75, or 0.007～0.875 based on your die interface profile.

For ball-lock punches, confirm fit by checking the punch diameter compatibility with the ball-lock pocket/housing dimensions in your die design. Because tolerance values are not provided in the input data, verify tolerances against your housing spec before finalizing the dimension set.
