Ball Lock Regular Punches - Light Duty, Inch, XNP Coating

These light-duty ball-lock punches are used in injection mold tooling and dies where the punch must stay securely retained and deliver repeatable ejection during frequent press cycles. The ball-locked tip geometry helps maintain stable contact, reducing the risk of tip shift and supporting consistent part ejection in compact, indexed setups.

• Progressive die stations: Ideal for trimming and forming operations that require reliable punch retention and predictable stroke-to-stroke performance, especially when multiple tools are mounted close together.
• Die maintenance and refurbishment: The XNP coating variant supports routine forming and trimming by improving surface durability, helping punches resist wear in maintenance-heavy environments.
• Light-duty housings and brackets: Suitable where modest forming loads benefit from controlled punch control using selectable tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) and coded inch point lengths.

Choose this variant when die life and repeatability matter more than maximum heavy-duty toughness.

This series is available in M2 or PS4 material options, intended for light-duty die applications. M2 (high-speed steel family) is typically selected when higher wear resistance is needed; it is generally supplied in a hardened condition for good edge stability under repeated cycling. PS4 is offered as an alternative material choice for users optimizing for cost/performance in routine forming and trimming.

• XNP coating: Applied to improve surface durability and help reduce abrasion-related wear during standard die operations.
• Hardness/heat treatment state: The exact HRC and heat-treatment recipe are not specified in the provided metadata, so select based on your supplier’s material certificate for the exact hardened or treated state.
• Trade-offs: In general, higher-wear steels prioritize hardness, while softer-tougher choices can better tolerate minor misalignment at the expense of wear rate.

Confirm final hardness (HRC) and coating system details with your purchase documentation for critical wear targets.

Select the correct punch size by matching the shank diameter D and the coded point length L to your mold/die cavity/core requirements. This series provides D (Shank dia.) from 25 to 100 in and multiple L length ranges (coded inch) depending on the point-length configuration.

• Choose D first: Ensure the shank diameter (25–100) matches the guide/bushing or hole diameter requirement in your die set with your intended fit.
• Select the point length by format: For “Standard Point Length & L,” ranges include 200–500, 200–600, 200–700, 225–700, and 225–700 (as listed). For B/C/D point-length groupings, use the provided ranges such as B & L: 225–500 / 225–600 / 225–700, C: 225–600 / 225–700, and D: 250–700.
• Use P and W geometry limits: Keep your design within P = 0.04–0.75 in and W = 0.04–0.437 in, and respect the small R = 0.007 in value listed.

Tolerance guidance is not specified in the provided data; therefore, verify assembly fit (guide clearance and retention) against your die standards and purchase drawings.
