Inch Ball Lock Regular Punches Light Duty XNA Coating

Light-duty inch injection and press tooling uses these ball-lock regular punches to ensure positive cavity/core alignment and stable ejection. In automotive connector and small housing mold builds, the ball-lock retention helps maintain punch position during repeated press cycles, reducing drift that can affect part fit and cosmetic consistency.

• Blanking and light forming: XNA-coated surfaces support longer punch life where abrasive loads and frequent start/stop cycles occur.
• General die sets for inch molds: the precise ball-lock fit improves part positioning stability and supports repeatable ejection performance.
• Mixed material inserts: compatible shank diameters and coded point lengths allow matching to standard die layouts while keeping light-duty wear under control.

The selected variant is suited for these applications because it combines ball-lock retention with an XNA coating engineered for wear resistance and predictable tool behavior in routine production.

This series is offered in M2 and PS4 tool steel options, selected to balance hardness, wear resistance, and toughness for light-duty inch tooling. While exact hardness values are not listed in the provided specifications, M2 is commonly used for applications needing higher wear resistance under sliding/impact conditions; PS4 is typically selected when a different toughness/maintenance profile is preferred for forming and die-set environments.

• XNA coating: a wear-supporting surface layer that reduces abrasive deterioration at the punch tip and along the active working area.
• Heat treatment state: the dataset does not specify the tempering/nitriding condition, so material performance should be validated against your supplier’s tool-heat-treatment data for final HRC targets.
• Trade-offs: increasing wear resistance generally increases sensitivity to chipping, so choose the steel grade and tip geometry according to forming load and cycle count.

For most light-duty press and die-set work, the M2 option with XNA coating is a strong starting point; PS4 can be considered where a different balance of toughness and tool life is required.

Select dimensions by matching the shank and point characteristics to your mold’s locating features and the punch working stroke. The shank diameter D ranges from 25 ~ 100 in (inch tooling), so confirm your press/die-set plate pocket size before ordering.

• Tip shape: choose from H, J, K, L, N, O, R, V, X, Y, Z to match your cavity/core geometry requirements and desired entry profile.
• Point length L: coded inch lengths include 200 ~ 500, 200 ~ 600, 200 ~ 700, and 225 ~ 700 depending on configuration.
• Ball-lock feature lengths: B and C variants are specified by ranges such as 225 ~ 500, 225 ~ 600, 225 ~ 700 (B) and 225 ~ 600, 225 ~ 700 (C), while the D point length runs 250 ~ 700 (as coded).

For fit, use the P and W dimensions (0.04 ~ 0.75 and 0.04 ~ 0.437) and the R dimension (0.007 ~ 0.007) to align with your ball-lock pocket geometry. Any tolerance/fit requirements are not provided here, so match to your locating/ball-lock spec and verify tool-to-pocket clearance during tryout.
