Ball Lock Regular Punches Heavy Duty Inch XNM-Coated

This heavy-duty ball lock punch is used in injection and press-adjacent tooling where dependable ejection is required after forming cycles. The ball-lock geometry supports strong retention in the tool block, helping maintain alignment and reducing tip movement under repetitive load.

• Automotive connector and terminal housings: In progressive or insert-press operations, the XNM-coated tip helps protect the working surface so ejection remains consistent across long production runs.
• Appliance and consumer product brackets: The inch-coded standard point length options (e.g., 250–700 coded inch ranges) make it easier to match common die-set stack heights for stable part release.
• High-cycle press operations: The heavy-duty style suits continuous cycles where wear resistance at the punch face and reliable retention are critical for dimensional stability.

Select the XNM-coated variant when your process experiences abrasive wear or frequent cycling that can otherwise degrade punch surface condition over time.

The punch is offered in M2 or PS4 steel options, selected based on target wear resistance and toughness balance. M2 (tool steel commonly used for high-wear applications) is typically selected when you need strong abrasion resistance at the tip under repeated contact, while PS4 is positioned as an alternative material choice for durability in demanding tooling conditions.

• M2 option: favors wear resistance for long production intervals; performance depends on the selected heat-treatment condition provided by the manufacturer for this component series.
• PS4 option: used as a configurable steel alternative when you balance tooling life and toughness requirements for your specific press duty.

For the working surface, the XNM coating improves surface protection to reduce wear progression during service. Exact hardness (HRC) and heat-treatment state are not specified in the provided data, so verify with the series’ material certificate for quenched-and-tempered, nitrided, or other treatment details.

Choose dimensions to match your die-set cavity/core stack and the required punch reach. Start with D (shank diameter), available in the 37–125 in range, and confirm it fits your tool block bore while maintaining proper guidance.

• Point length L: coded inch lengths are offered in sets such as 250–600, 250–700, 275–700, and 300–700. Pick the code range that corresponds to the total required protrusion from the tool face.
• Point length B / C / D: the same coded inch ranges are listed (e.g., 250–600, 250–700, 275–700, 300–700, or narrowed options like 275–700 and 300–700 for certain variants). Use the relevant point-length designation that your drawing references.
• Extra geometry: P (0.05–1 in) and W (0.05–0.5 in) are configurable by tip shape; ensure these match your die clearance and forming/ejection interference constraints.

If you have tight fit requirements, confirm the series’ tolerances for shank diameter D and the tool-block bore; the provided data lists dimensions and ranges but not specific tolerance grades.
