Point Larger than Shank Regular Ball Lock Punches - Heavy Duty, Metric

This heavy-duty metric ball-lock punch set is used in injection molding and press-style tooling where a dependable locator/stripper action is required. The point is larger than the shank, which improves ball-lock retention so the punch maintains position during repeated load cycles.

• Automotive connector and housing molds: Suitable for maintaining stable cavity/core alignment and consistent ejector behavior under frequent switching and tight dimensional repeatability.
• Electronics enclosures and clips: The larger point geometry helps secure the punch during high-cycle production, reducing risk of tool micro-movement that can affect part geometry.
• Appliance and industrial component molds: Used for robust stripping/locating in tooling stacks where wear resistance matters; the XNA coating supports longer punch life by improving surface wear performance.

Use the available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) to match gate geometry, part ribs, or draft-related contact requirements without changing the overall mounting concept.

The provided metadata focuses on geometry and coating rather than the base steel grade. Based on the specification, this variant uses an XNA coating system to improve wear resistance and help maintain stable punch performance over production runs.

• Coating benefit (XNA): Higher resistance to abrasive wear at the point contact zone, supporting longer service intervals and reduced dimensional drift.
• Hardness/toughness trade-off: While coating increases surface durability, punch body toughness is typically governed by the underlying steel and heat treatment; avoid over-selecting for maximum hardness at the expense of shock resistance in high-impact stripping.
• Heat treatment state: Not specified in the input data, so base hardness (e.g., HRC) and specific processes (nitriding/quenching & tempering) cannot be confirmed from the provided parameters.

If you need a confirmed steel grade and target hardness (HRC) for qualification, share the preferred supplier drawing or request the material certificate for series 250000001682.

Correct selection is driven by the shank diameter (D) and point geometry. Choose D from the allowed metric options: 13, 16, 20, 25, 32, 40 mm. Match the punch to the mating ball-lock pocket and any stripper/locator bush bore so the shank can seat without interference.

• Point length (L1): fixed range 19–30 mm. Use this to control how deep the point engages for locating/stripping.
• Total length (L): fixed range 80–100 mm. Select based on your tool stack height so the punch protrusion is correct at maximum compression.
• Point/geometry parameters: P varies 13.1–40.1 mm, W varies 1.57–34.73 mm, and R is selectable within the provided step ranges (e.g., 0.2–16, 0.2–19, 0.2–20, 0.2–22, 0.2–25, 0.2–28 depending on the option). These govern contact area and stress concentration at the point.

Tolerance/fit: because D and the ball-lock retention system are critical, specify the corresponding pocket clearance from your internal standards; the larger point “than shank” should be checked against cavity/core recess dimensions to prevent interference at full stroke.
