Product Guide
Application Scenarios+
This heavy-duty ball-lock pilot punch is used in injection and insert tooling to establish repeatable alignment between an upstream forming stage and the final punch cavity. The tapered tip improves lead-in guidance, helping reduce misalignment during high-cycle punch operations.
- Automotive connector and terminal housings: Use as a pilot in progressive dies to maintain consistent positioning of small features, where wear-stable guidance improves dimensional stability across production runs.
- Appliance and consumer electronics housings: Suitable for multi-step tooling because the ball-lock guidance supports stable part location even when feed accuracy varies slightly.
- Medical device component housings: Recommended where consistent alignment reduces scrap risk; the XN DayTride® coating helps limit friction and supports longer service intervals under frequent cycling.
Available steel options and the coating make this variant well-suited for guided alignment in tooling that demands reliable pilot repeatability.
Material & Process Details+
This product is supplied in M2 or PS4 steel, both designed for durable, hardenable performance in pilot punching applications. When selecting between them, consider performance and toughness needs: M2 typically supports higher hot-work abrasion resistance, while PS4 is chosen when robust toughness and stable wear behavior are prioritized for tooling cycles.
- M2: AISI M2 equivalent; commonly used with quench-and-temper heat treatment to reach high hardness and strong wear resistance.
- PS4: Tool steel grade available for hardened performance; heat-treated to achieve a balanced hardness/toughness level for punching and alignment components.
- XN DayTride® coating: Surface treatment that helps reduce friction and improves wear life at the guided contact interface.
Exact hardness in HRC is not specified in the provided data; final hardness should be verified per the delivered lot and coating/heat-treatment specification to match your press load and duty cycle.
Sizing & Selection Guide+
To select the correct pilot punch dimensions, match the shank diameter D, the overall length L, and the tip geometry to your mold/tooling layout and guide requirements. This series offers D = 10 ~ 40 mm and P (tip diameter) = 1.45 ~ 30 mm, with multiple point-length options to fit different cavity depths.
- Match D to the guide hole/receiver: Choose the shank diameter within 10–40 mm that corresponds to the mating guide bore in your tool block.
- Set engagement using L1 (point length): Select L1 from 19–62, 19–92, 25–102, or 30–102 mm to ensure sufficient tapered guidance without bottoming.
- Confirm reach using L: Overall length is available as 80–110, 80–140, or 80–150 mm depending on configuration.
- Tolerance/fit: Use the provided metric dimensions as selection bounds; final clearances should be set by your tool’s hardened receiver tolerance to maintain smooth ball-lock action and prevent side-load wear.
All dimensions in this series are variable, so verify your intended configuration (L1 and L pairing) during design freeze.
