Metric Ball Lock Pilot Punches Round Tip XNAP Coating

Ball-lock pilot punches are used to establish repeatable part-to-die registration in metric injection and precision molding tooling. The round-tip ball-lock geometry helps the punch self-center during engagement, supporting stable locating through production cycles.

• Automotive connector and housing molds: Use the metric shank diameter (D = 6 to 38 mm) and selected point length (L1 = 12–32 mm ranges) to ensure consistent pilot contact while guiding slides or inserts during runner/housing molding.
• Appliance and industrial housings: Choose the appropriate overall punch length (L = 65–127 mm depending on configuration) to match cavity/core engagement depth, reducing misalignment risk during repeated shutoff.
• General forming and pilot operations: The XNAP-coated surface is suited for wear-sensitive pilot locations where long-term locating stability matters.

XNAP coating supports improved wear resistance at the pilot interface, helping maintain consistent fit and alignment in day-to-day production.

This series is available in M2 and PS4 materials, allowing selection based on wear vs. toughness needs. M2 is a high-speed steel grade commonly used where cutting-edge and locating features must resist abrasion; it typically balances high wear resistance with good toughness after heat treatment.

• M2: Usually delivered in a hardened condition (exact state not specified in the provided data). Expect strong wear performance for repeated pilot engagement and frequent mold cycles.
• PS4: Selected when a different balance of properties is preferred for pilot components. Compared to M2, PS4 may be chosen to optimize durability for specific tooling conditions (exact hardness and treatment not specified).

Manufacturing typically involves precision grinding of the ball-lock tip to maintain stable fit, followed by coating application for XNAP wear support at the locating surface.

Select dimensions to match the pilot interface depth and ensure controlled engagement between the punch and its corresponding pilot hole features in the mold. Start with the shank diameter D (6–38 mm) to match the locating clearance and bore size in the mold base or bushings for metric tooling.

• Choose point length L1 from the available ranges (12–15, 12–21, 15–27, or 21–32 mm) based on how far the ball-lock tip must reach for reliable centering.
• Choose overall length L from the available configurations (65–102, 65–112, 65–127, 73–127, 92–127, or 112–127 mm) to fit within the die thickness and mounting stack-up without bottoming.
• Verify P dimension (1.55–11.95 mm) to confirm the required locating geometry for the ball-lock interface.

Because the data provides range-based variants rather than single fixed values, confirm the exact part code/variant for the cavity/core shutoff depth and the pilot-hole bore target in your CAD and try to maintain specified assembly clearances for repeatable fit.
