Inch Ball Lock Regular Punches (XNM Coated, Light Duty)

In injection mold and precision die tooling, these light-duty ball lock punches are used to provide consistent, secure part ejection while maintaining stable alignment inside the cavity. The compact ball-lock retention helps the punch stay positioned through repeated cycles, reducing variation in ejection force and helping achieve cleaner part release.

• Automotive and industrial connector molds: Commonly used for ejecting small components where tight retention and repeatable punch travel matter. The M2 base steel supports durability under frequent forming cycles, while the XNM surface coating helps resist wear during standard production loads.
• Appliance and consumer housing inserts: Suitable for controlled ejection in molds with moderate wear demands. The ball-lock design improves mechanical positioning reliability, which supports stable ejection timing and reduces the risk of punch-to-cavity misalignment.
• General-purpose die assemblies: Used when a regular punch geometry and light-duty performance are sufficient. The available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) enable engineers to match part undercuts and ejection access.

This punch is offered with M2 steel (also listed alongside PS4) as the primary tool steel for wear-focused applications. M2 is an AISI M2 equivalent high-speed steel grade, selected for its balance of wear resistance and toughness under repeated contact loads.

• M2 steel variant: Typically hardened and tempered to achieve high hardness for edge/working-surface longevity, supporting stable performance during light-duty ejection.
• XNM coating (when specified): A surface treatment that improves durability by reducing wear during repeated forming cycles, helping limit abrasion at the punch face.
• Material trade-off: Compared with M2, PS4 availability indicates an alternative option when different hardness-to-cost or application-specific wear characteristics are desired.

Choose the coated M2 configuration to maximize wear resistance while maintaining adequate toughness for frequent mold cycling.

Use the shank diameter and coded length ranges to match your cavity/core ejection layout. The shank diameter D is available from 25 ~ 100 in, so select the closest diameter that fits the supporting plate/tooling bore without excessive clearance.

• Length selection (L / coded inch): Point length and overall length are offered in multiple coded ranges such as 200 ～ 500, 200 ～ 600, 200 ～ 700, 225 ～ 700, and 225 ～ 700 (as listed), with additional options including 200 ～ 600 and 225 ～ 700 variants depending on configuration.
• B/C/D point-length variants: Point-length coded ranges are also listed separately (e.g., B: 225 ～ 500, 225 ～ 600, 225 ～ 700; C: 225 ～ 600, 225 ～ 700; D: 250 ～ 700 and 250 ～ 700).
• Clearance & fit: Match D to the ejection guide bore/plate to ensure smooth travel and reduce wobble. Maintain appropriate working clearances so the ball-lock retention can function consistently without binding.

Confirm tip shape (H, J, K, L, N, O, R, V, X, Y, Z) against part undercut/access to ensure effective contact during ejection.
