Ball Lock Ejector Punches Heavy Duty Inch XN DayTride® Coating

Ball lock ejector punches are used in precision die sets where components must be ejected reliably without shifting or drifting during repeated press cycles. This heavy-duty inch punch style is well-suited to automotive and industrial connector housings, where stable ball-lock retention helps maintain alignment through high-volume molding runs.

In appliance and metal-replacement appliance parts, the hardened-steel body plus XN DayTride® coating supports controlled ejection accuracy and mitigates abrasive wear on the working surfaces when cycles are frequent and tolerances are tight.

For medical device housings and caps, consistent punch positioning reduces the risk of part damage during ejection. The available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow engineers to tune contact geometry for the product and ejector layout, while the coated surface improves longevity in maintenance-sensitive die operations.

• Secure ball-lock retention for stable die operation during ejection cycles
• Heavy-duty inch format for production mold die sets
• XN DayTride® coating to reduce wear in demanding tooling environments

This series supports M2 or PS4 steel options, with hardened-steel construction intended for dependable punch performance in wear-critical ejection tasks. M2 is commonly chosen when higher hot hardness and tool-steel toughness are needed for durable punch tooling under repeated cycling, while PS4 provides an alternative steel selection for specific performance targets.

The XN DayTride® coating is engineered to reduce friction and improve wear resistance at the punch/insert interface. In hardened tooling conditions, this helps limit surface degradation that can affect ejection repeatability.

• M2 option: intended for robust punch strength in heavy-duty applications
• PS4 option: alternative steel choice for matching tooling performance requirements
• Coating (XN DayTride®): supports wear reduction for longer punch life

Note: The provided data specifies material grades and coating; it does not list the exact hardness (HRC) or the detailed heat-treatment state (e.g., quenched & tempered vs. nitrided), so those values should be confirmed on the specific order drawing.

Correct sizing for ball lock ejector punches starts by matching the shank diameter D and the point/working length options to your mold core/ejector layout. From the provided specs, D (shank dia.) is available in the range of 37 ~ 125 in (inch format as listed), so select the nearest diameter that matches the ejector guide and ball-lock receiving components.

Working length is offered through coded inch ranges. Choose a standard point length L within 250 ～ 500, 250 ～ 600, 275 ～ 600, or 300 ～ 600, depending on how far the punch must enter the part plane and clearance requirements.

• Match D to the die set’s guide/bore requirements for proper ball-lock engagement
• Verify L (and the applicable point length variant among B/C/D) against ejection stroke and shutoff depth
• Confirm P (0.062 ~ 1 in) and W (0.062 ~ 0.5 in) are compatible with the cavity geometry and interference limits
• The listed R dimension (0.007 ~ 0.007 in) is fixed in range; ensure your contact radius requirements match
