Metric Light Duty Ball Lock Pilot Punches - Tapered Tip

These light-duty ball lock pilot punches with a tapered tip are used in metric die and press assemblies to establish repeatable part-to-die alignment and stable punch guidance during cycling.

• Automotive and general metal-stamping die sets: the ball-lock retention helps prevent pilot drift, while the tapered nose improves centering as the punch enters the mating pilot/guide features, supporting consistent ejection timing and reduced scuffing.
• Electronics and small component forming: for smaller die openings, the tapered tip promotes controlled engagement at the start of each stroke, improving positioning accuracy when tolerances are tight.
• Die assemblies with frequent die changes: standardized, ball-lock locating improves repeatability across setups, helping maintenance teams verify alignment after reloading tooling.

Choose this variant when you need dependable retention and easier entry due to the tapered geometry, while staying within a light-duty build profile for die operations.

Material and heat-treatment details are not provided in the supplied product metadata for this series, so the selection and hardness values must be confirmed in the series datasheet before specifying for wear-critical duty.

For ball lock pilot punches, engineers typically prioritize wear resistance at the tip and toughness to resist chipping from misalignment or vibration. The tapered point geometry places more contact load during initial engagement, which can increase surface wear if the steel is under-hardened.

• Hardness trade-off: higher hardness improves sliding/wear performance but can reduce toughness if over-tempered.
• Common heat-treatment routes (for reference): quenched & tempered steels are typical for balanced toughness/wear; nitriding/carburizing is used when maximum surface wear resistance is required.

Please verify the exact steel grade and target hardness for series 250000002032-034 to ensure compatibility with your die material, load, and cycle rate.

Select the pilot punch size by matching the shank diameter (D), point length (L1), and overall length (L) to the mating die set geometry.

• Shank diameter D (mm): choose within 10 ~ 38 based on the required pilot hole/guide clearance and alignment feature size.
• Point length L1 (mm): available as 19–72, 19–102, 25–112, or 30–112. Use L1 to ensure sufficient tapered engagement before full pilot guidance starts.
• Overall length L (mm): available ranges include 71–110, 71–140, 71–150, or 80–150. Set L so the punch reaches the required stroke position without bottoming against the mating component.

The P dimension (mm): 1.45 ~ 30 should be matched to the ball-lock/pilot geometry requirement in the mating die feature. Confirm tolerance/fit for the D and ball-lock engagement surfaces per your die standard; the ball-lock system is intended to improve retention, but clearance still affects alignment stability.
