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

These ball-lock pilot punches are used in injection mold and die tooling to create repeatable, indexed positioning between components such as mold base sections, cavity/slide carriers, and mating insert assemblies. The round tip supports stable pilot contact, which is especially helpful when alignment loads are moderate and long-term repeatability is required.

• Automotive and appliance connector molds: Use the metric light-duty round tip for locating of thin, precision components where consistent alignment reduces mismatch at parting lines.
• Medical device housings and ergonomic fixtures: The controlled pilot geometry helps maintain cavity-to-core registration during assembly and maintenance cycles.
• General mold base/die component pairing: The ball-lock pilot principle improves repeatability during tool build-up and teardown.

The XNT DayTiN® coating is suited to repeated contact environments, supporting longer wear life on the punch tip during mold machining and assembly fit-up.

This light-duty pilot punch series is offered in two material options: M2 and PS4. M2 is a high-speed steel grade typically selected for its balance of wear resistance and toughness under intermittent cutting and contact-related stresses. PS4 is commonly chosen when good hardness and stable performance under machining contact are needed, while offering a practical alternative based on shop preference.

• Wear resistance: The XNT DayTiN® coating enhances surface durability during repeated punch-to-feature contact.
• Hardness & trade-offs: Steel hardness level will depend on the supplied heat-treatment condition (not specified in the provided data). Higher hardness generally improves wear resistance but can reduce toughness if over-aggressive for impact loads.
• Heat treatment state: Select the heat-treated condition consistent with your supplier’s process for M2/PS4 to ensure the intended hardness and dimensional stability.

Correct sizing ensures the ball-lock pilot punch seats properly and delivers repeatable alignment. Start by matching the shank diameter D to the mating guide/bore: available D values are 6 ~ 38 mm. Then select the appropriate point length (L1) based on how much engagement is required at assembly; your L1 options span 12–15, 12–21, 15–27, or 21–32 mm (as listed per configuration).

• Total length L: Choose from the provided L ranges such as 65–102, 65–112, 65–127, 73–127, 92–127, or 112–127 mm, ensuring clearance from adjacent steel, ejector components, and retainer hardware.
• Ball-lock engagement: Match the P dimension (1.55 ~ 11.95 mm) to the mating ball-lock feature geometry so the locating action reaches the intended depth.

For fit, use the punch’s metric geometry to align tolerances with your molded component registration targets; confirm clearance and press/fit expectations in your drawing set before final lock-in.
