Metric Ball Lock Pilot Punches - Round Tip, Light Duty, XVP

Metric ball-lock pilot punches are used to establish repeatable part-to-die alignment in light duty forming and punching operations. In these tooling setups, the round tip and ball-lock geometry help stabilize pilot contact so the press cycle can “find” the correct position each time, improving hole-to-feature concentricity.

• Automotive and appliance brackets (progressive forming): Use the metric sizing to match standard pilot systems, especially where quick setup and consistent feed alignment reduce scrap from misregistration.
• Consumer electronics housings (punching/bending operations): The round-tip pilot supports smooth guidance during entry, which is helpful for thin-wall or sensitive geometry where alignment must be maintained over multiple stations.
• General tool & die shop jigs: XVP coating supports long cycle wear performance in frequent dry-running conditions, helping reduce friction-related wear at the pilot interface.

The XVP-coated variant is particularly suited for light duty tooling that prioritizes reliable pilot guidance with improved wear and reduced friction under repeated cycling.

These light duty pilot punches are available in M2 and PS4 steel options, selected to balance wear resistance and toughness for pilot guidance applications. M2 is a high-speed tool steel commonly associated with AISI M2 / equivalent performance, offering good abrasion resistance for the tip and shank during repeated indexing. PS4 is typically used where stable machinability and cost-efficient tooling performance are desired, while still providing adequate wear characteristics for pilot location in light duty dies.

• Heat treatment state: Supplied as hardened tooling components; specific heat treatment parameters are not provided here, so verify with the individual part print for exact target hardness and procedures.
• Hardness & trade-offs: Higher hardness generally improves wear resistance of the pilot tip, but can reduce impact toughness. Choose the steel based on cycle severity and any vibration/side-loading at the pilot interface.
• Wear resistance: XVP coating further reduces friction and helps protect the contact area from wear during cycling.

For the highest tip wear performance in abrasive conditions, M2 is typically the preferred choice; for lighter duty or cost-sensitive builds, PS4 may be selected depending on expected loads.

Select the ball-lock pilot punch dimensions by matching the shank diameter (D) and point length (L1) to the corresponding pilot hole/bore and engagement depth in your die set. The goal is reliable ball-lock engagement with sufficient guidance length to prevent lateral drift during forming or punching.

• Shank diameter (D): Choose from 6 ~ 38 mm to match your die pilot bore size and maintain proper fit within the metric pilot system.
• Point length (L1): Available ranges are 12–15, 12–21, 15–27, or 21–32 mm. Use the L1 range that provides the desired pilot tip engagement without bottoming.
• Total length (L): Options include 65–102, 65–112, 65–127, 73–127, 92–127, and 112–127 mm. Select L to ensure clearance to adjacent components and correct protrusion at assembly.
• P dimension: Match P = 1.55 ~ 11.95 mm to the ball-lock feature geometry specified for your pilot system.

Confirm tolerances using your die blueprint and the punch drawing; pilot systems typically require tight clearance for smooth entry while maintaining positional repeatability.
