Inch Standard XVP Coated Ball Lock Pilot Punches - Round Tip

In injection mold tooling, ball-lock pilot punches are used to establish repeatable cavity-to-core and slide-to-station alignment, especially in inch-based die builds where location accuracy directly affects part geometry and shutoff consistency.

• Automotive connector and housing tooling: The round tip geometry supports dependable centering for consistent pilot location across production cycles. The heavy-duty punch configuration helps maintain alignment under higher load conditions, while the XVP coating improves resistance to rubbing wear at the pilot interface.
• Industrial enclosure and appliance components: Use these punches to stabilize alignment between die sections during setup and restart. The inch-standard availability and defined shank diameter range allow integration with existing tooling hole patterns and die blocks.
• Packaging and consumer part molds with frequent job changes: The controlled pilot geometry helps reduce indexing drift when tooling is removed and reinstalled, supporting consistent part positioning.

This series is offered in M2 or PS4 to match different wear and toughness needs common in pilot tooling.

• M2 (typical high-speed steel behavior): Designed for high wear resistance. In applications involving frequent engagement of the pilot interface, M2’s hardness supports longer service life; a trade-off is that toughness may be lower than more ductile grades if impact loading is severe.
• PS4: Typically selected when balanced toughness and good cutting/punching performance are prioritized for tooling components. It can be a practical choice where you want reliable performance without relying on extreme hardness alone.

Specific hardness (HRC), heat-treatment state (e.g., quenched & tempered, nitrided), and coating thickness are not provided in the input data; however, the included XVP coating is intended to enhance wear resistance at the contact surface during repeated pilot engagement.

To select the correct ball-lock pilot punch size, match the shank diameter D and the required standard point length L to your mold’s pilot bore location and tool stack-up.

• Shank diameter D (in): Choose a value within 37 ~ 125 (as provided by your inch-standard selection system). This ensures the punch fits the receiving pilot hole size without binding.
• Point length & L (coded inch): Select from the available ranges: 250 ~ 600, 250 ~ 700, 275 ~ 700, or 300 ~ 700 (depending on the exact option). If you need longer engagement, the variants also show a narrowed option such as 275 ~ 700 and 300 ~ 700.
• P dimension (in): Confirm 0.061 ~ 0.999 matches your required protrusion and contact depth at the pilot interface.

Maintain proper clearance in the die receiving pocket and verify that your pilot engagement depth supports repeatable centering without excessive interference. Use the coded length options (L, B, C variants listed) that correspond to your drawing’s required engagement geometry; dimensions labeled as options are configurable, while engagement requirements come from your cavity/core location scheme.
