M2 Steel Ball Lock Ejector Punches Heavy Duty XAN DayTAN™ Coating

Ball lock ejector punches with a hardened M2 steel core are used in metric die sets where reliable part ejection must be maintained over long production runs. The ball-lock geometry improves retention of the punch body in the ejector system, helping prevent drift during repeated press cycles.

• Automotive interior and connector housings: These heavy-duty ejectors support consistent ejection of molded components with uniform undercuts, reducing the risk of incomplete release at cycle rates where ejector stability is critical.
• Appliance and industrial enclosure parts: Use with die tooling that needs repeatable stroke behavior; the XAN DayTAN™ coating is selected to improve surface wear performance in abrasive or high-cycle molding environments.
• Consumer electronics housings: Point-shape options enable compatibility with different part-release contact geometries while maintaining a secure lock during production.

This variant is suited because it combines an M2 material base with the XAN DayTAN™ coating and a heavy-duty ball-lock design for stable performance in metric die applications.

This series is offered in M2 steel (also known as a high-speed steel commonly used in tooling). M2 is typically chosen for its strong wear resistance and good toughness balance under repetitive contact and sliding in ejector systems. The XAN DayTAN™ coating further enhances wear performance, supporting longer punch life in high-cycle molding.

• M2 option: Used when hardness and abrasion resistance are priorities for stable ejection over repeated press cycles.
• PS4 option: Provided as an alternate material selection for differing application requirements; compare based on expected wear intensity and tooling contact conditions.

Heat treatment is assumed to be the standard for ejector applications using the selected steel grade, producing a hardened cutting/tooling state suitable for load-bearing ejector duty. If you need exact HRC or the specific heat-treat recipe, confirm with the quoted spec for your exact tip shape and length.

Select an ejector punch by matching the shank diameter D, overall length L, and the point length L1 to the die cavity/core ejector layout. For this series, D (shank dia.) is available from 10 ~ 40 mm, so choose the diameter that matches your ejector bushing or guide bore requirement for the metric die set.

• Overall length (L): options include 63 ~ 100, 63 ~ 125, 71 ~ 125, and 80 ~ 125. Use this to ensure proper stroke clearance and full ejection travel without bottoming.
• Point length (L1): choose among 10 ~ 19, 13 ~ 25, or 19 ~ 30 mm to set the contact depth on the molded part.
• Tip shape: pick from H, J, K, L, N, O, R, V, X, Y, Z to fit the required contact geometry and part release interface.

Coordinate P (1.5 ~ 39.971 mm) and W (1.5 ~ 14 mm) with the ejector contact/clearance zone. Maintain tooling alignment for ball-lock engagement; tolerance/fit guidance should follow your die block and bushing specification since these values are provided as ranges for compatibility.
