Ball Lock Ejector Punches Heavy Duty, Inch X-Shaped Tip

Ball lock ejector punches with an X-shaped tip are used in injection and press tooling where positive retention and repeatable ejection are required. In progressive dies and industrial stamping, the X geometry helps maintain secure locking contact during repeated cycling, reducing the risk of lockup drift that can lead to inconsistent part release.

They are also suitable for automotive and appliance component dies that run long production cycles. The heavy-duty inch sizing supports stable ball-lock engagement under continuous loading, improving ejection accuracy and repeatability across many strokes.

For die operations involving fine alignment features, these punches are designed to work with controlled assembly positioning. Engineers can match shank diameter and overall coded length to the mating housing/ball-lock pocket so that the locking interface forms reliably and ejects parts consistently.

• X-shaped tip promotes reliable ball-lock retention during cycling
• Inch heavy-duty build targets long-term durability in production environments
• Dimension matching supports consistent alignment and ejection accuracy

The provided specification set identifies this as a DAYTON heavy-duty inch ball lock ejector punch with an X-shaped tip, but it does not list the steel grade, hardness (HRC), or a stated heat-treatment condition. As a result, specific data such as “SKD61/H13 equivalent” or “quenched & tempered to X HRC” cannot be verified from the input.

In typical mold and die practice, ball-lock punches balance wear resistance at the tip interface with toughness to resist bending and impact during ejection. If you require confirmed material properties (grade, target HRC, and whether nitriding or other surface treatment is used), you should request the lot-specific cert from the supplier for engineering sign-off.

• Unknown from provided data: steel grade, target hardness, and heat treatment state
• Selection principle: prioritize wear resistance at the tip while maintaining toughness under cycling

Select dimensions by matching the punch to the mating ball-lock pocket and the guide features in your tooling stack. This series is configured by tip shape (here X) and a set of variable inch dimensions.

• Shank diameter (D): choose within 37 ~ 125 in as specified for the required guide/support clearance.
• Length (L): use the coded inch length range 250 ~ 450 or 275 ~ 450 to ensure correct protrusion and engagement depth inside the ejector system.
• Ball-lock interface geometry: match P (0.376 ~ 1.251 in) and W (0.062 ~ 1.083 in) to the mating retention features to maintain stable locking contact.
• Tip/R dimensions: select the appropriate R range (0.007 ~ 0.4375, 0.007 ~ 0.625, 0.007 ~ 0.75, 0.007 ~ 0.875, or 0.007 ~ 1) based on the required corner radius/contact profile.

Tolerance/fit: the input does not provide tolerance values, so confirm fit allowances with your die drawings for locking engagement and guide alignment.

Dimensions are configurable within the listed ranges; the tip shape is fixed to X for this variant.
