Ball Lock Ejector Punches - Light Duty, Inch XN DayTride Coating

These light-duty ball lock ejector punches are designed for inch-based injection tooling where knockout reliability and controlled friction at the interface are critical. The ball-lock retention style helps keep the punch aligned in the holder, supporting consistent ejection stroke repeatability across short to medium runs.

• Automotive interior and connector housings: Use for blanking and ejection in housings that see frequent part variations; the XN DayTride coating helps reduce galling so thin cores and surfaces maintain stable contact during ejector actuation.
• Appliance and consumer product covers: Suitable when light-duty knockout is required and minimizing wear at the tip supports longer tooling life, particularly with repetitive start-stop molding cycles.
• General electronics housings: The standardized inch workflow and secure retention reduce the risk of misalignment, improving ejection consistency for small features.

Choose this variant when you need smoother ejection with light-duty loads while maintaining stable mechanical retention in ball lock holders.

Two materials are available for these punches: M2 and PS4, allowing selection based on wear versus toughness priorities. M2 is a high-speed steel commonly used for excellent abrasion and edge retention; it is typically supplied in a quenched and tempered condition, balancing hardness with toughness. PS4 is used where forming and wear behavior under light-duty ejection is prioritized, providing an alternative hardness/toughness balance for smoother punch performance.

• Wear resistance: M2 generally offers stronger wear capability for repeated blanking and knockout at the tip.
• Toughness trade-off: Very high hardness can reduce impact tolerance; selecting PS4 may better suit tooling that experiences occasional uneven load during ejection.
• Surface performance: The XN DayTride coating further improves friction control and supports stable ejection by helping limit galling at contact regions.

For final performance, match the material choice to your ejection force profile and expected wear rate.

Select the punch shank diameter and length to match the core/cavity ejector design and the holder’s retention system. The shank diameter D (in) is specified in the range 25 ~ 100, so choose a D that matches the corresponding punch bore/holder spec in your inch tooling setup.

• Tip shape: Confirm the required tip shape code from H, J, K, L, N, O, R, V, X, Y, Z to suit the knockout geometry of your part.
• Point length (standard): Standard point length & L are coded in inch ranges such as 200 ~ 400, 200 ~ 500, 200 ~ 600, 225 ~ 600, and 225 ~ 600 variants depending on configuration.
• Point length with B & L (coded): Choose a matching coded length set such as 225 ~ 400 / 225 ~ 500 / 225 ~ 600 (for B & L) or 225 ~ 500 / 225 ~ 600 (for C sets).

Ensure your specified L range supports full ejector travel without bottoming; if your holder uses tighter fits, select within the documented coded length to maintain proper engagement and clearance.
