Ball Lock Regular Punches Heavy Duty Inch XVP Coating

Ball lock punches with heavy-duty, inch-based sizing are used in injection press and die tooling where stable ejection and consistent punch retention are critical. In automotive connector and terminal forming dies, the ball-lock retention helps maintain punch position through repeated cycles, reducing shift-related ejection variation. The XVP coating is suited to such duty because it improves wear resistance at the punch-to-die contact regions.

• High-volume forming/blanking: use the ball-lock feature to support reliable alignment during long runs.
• Medical device housing insert-molding tooling: choose compatible point geometries (H, J, K, L, N, O, R, V, X, Y, Z) to match the cavity/core and part features, supporting clean ejection.
• General tool & die shops: the inch dimensions integrate directly into inch tool layouts, simplifying die builds.

Select the variant with the required shank diameter and coded length range to ensure the punch seats properly and ejects uniformly.

This punch series is offered in M2 and PS4 material options, supporting different balances of wear resistance and toughness for tool & die work. M2 is a high-speed steel commonly selected where higher hot hardness and cutting/impact resistance are beneficial, while PS4 is typically chosen when a different wear/toughness balance is preferred for press applications.

• Hardness & heat treatment: The provided data does not specify HRC or a defined heat-treatment recipe for these variants, so hardness should be confirmed per the selected material/heat lot before critical builds.
• Wear vs. toughness: M2-based builds generally favor wear resistance under demanding cycles; PS4 selections can be used where the shop prefers its toughness/wear behavior for specific forming loads.
• Coating effect: the XVP coating supports improved wear resistance at contact surfaces, extending usable life in abrasive or repetitive ejection environments.

For final design, match the material choice to expected press load, cycle rate, and the die steel compatibility.

To select the correct ball lock regular punch, start with the shank diameter D and then match the coded length L to the depth requirements of the die. Available shank diameter range is D = 37 ~ 125 in (per provided spec). Next, select the coded length option that fits your tool stack-up: L ranges from 250 ～ 600, 250 ～ 700, 275 ～ 700, or 300 ～ 700 (coded inch), depending on the configuration.

• Tip geometry: choose from H, J, K, L, N, O, R, V, X, Y, Z to align the punch point with your forming/blanking feature.
• Point length checks: the spec provides corresponding point-length codes (B, C, and D) with the same numeric ranges (e.g., 250 ～ 600 / 250 ～ 700 / 275 ～ 700 / 300 ～ 700). Use these to ensure adequate engagement without bottoming.
• Dimension tolerancing: the provided data lists functional variation ranges for P = 0.05 ~ 1, W = 0.05 ~ 0.5, and R = 0.007 ~ 0.007. Use these when validating clearances and contact pressure in the ejector system.

When integrating into the cavity/core design, verify the punch seating length and clearance to the mating die surface for consistent ejection force.
