DIN Standard Steel Ball Lock Pilot Punches - Tapered Tip

Where it’s used: These tapered-tip ball lock pilot punches are used in progressive and transfer injection tooling to set and maintain precise part location throughout repeated stamping and molding cycles.

• Automotive interior and connector components: In progressive die sets for small housings and brackets, the tapered tip improves centering during die feed and setup, helping reduce early-life misalignment when starting production or after tool changeover.
• Electronics enclosures and lightweight housings: For light-duty metric applications, stable pilot engagement supports consistent cavity-to-core registration, which is critical when multiple cavities require repeatable positioning.
• Medical device packaging and fixtures: When tight positional repeatability matters for downstream forming/assembly, the ball lock concept provides smooth punch action and consistent location under frequent cycles.

Why this variant fits: The tapered geometry supports reliable self-centering, while the XCD coating helps maintain wear resistance so the pilot maintains fit and alignment over time in light-duty metric production runs.

This product is described as a DIN standard steel variant with an XCD coating intended to improve wear resistance and help maintain fit during repeated cycles. The series information provided does not specify an individual steel grade or a defined heat treatment condition (e.g., quench-and-temper or nitriding), so material state and hardness values cannot be stated from the current data.

• Coating role: XCD is used to resist abrasive wear at the pilot interface, supporting stable centering performance and consistent engagement of the ball lock feature.
• Trade-offs (based on function): For light-duty applications, the goal is repeatable location with good toughness for normal operating loads rather than maximum wear life required for heavy-duty high-temperature tooling.

Selection note: If you need a specific DIN steel grade (e.g., H13-style hot-work steels or M2-type high-speed equivalents) or a hardness target (HRC), provide the required performance goal and duty cycle so the correct steel/heat treatment specification can be confirmed.

Select the appropriate pilot punch size by matching the metric shank diameter (D) and the point length (L1) / overall length (L) to the die layout dimensions and available stroke clearance.

• Shank diameter (D): Choose from 10 ~ 38 mm to fit the corresponding pilot bore/housing in your die steel.
• Point length (L1): Use the available ranges 19–72, 19–102, 25–112, or 30–112 mm depending on how much taper engagement you need for centering.
• Overall length (L): Match to your tool stack-up using one of the provided ranges: 71–110, 71–140, 71–150, or 80–150 mm.

P dimension (P): The ball lock/P-related dimension is 1.45 ~ 30 mm; select the value that corresponds to the ball lock seat geometry to ensure proper retention and location repeatability.

Tolerance & fit: To maintain consistent pilot engagement, ensure your die-side bore/seat dimensions match the intended fit for ball-lock systems and account for any coating buildup effects when specifying clearances.
