Product Guide

🏭Application Scenarios+

These tapered-tip, light-duty ball lock pilot punches are used in injection tooling to establish repeatable die-to-die alignment and reduce the initial locating shock during closing. The tapered nose improves guided entry, helping stabilize positioning in light-duty progressive and transfer dies where start-up force must be kept low.

  • Progressive die pilot stations: Use the inch locating body to maintain consistent registration across multiple press cycles.
  • Die sets for thin-wall or light assemblies: The tapered geometry supports smooth guidance, which is beneficial when parts require controlled, low-deflection positioning.
  • Multi-cavity alignment: Pair the appropriate point length to maintain steady centering for reliable cavity/core repeatability.

Built with M2 or PS4 options, the punches are suited to tooling environments that need hardened wear resistance at the locating interface. For die makers targeting accurate setup and consistent ball lock engagement, this variant helps deliver stable guided alignment without excessive insertion force.

🔧Material & Process Details+

Material is offered in M2 and PS4 for the locating interface. M2 is a high-speed steel option commonly selected for a balance of hardness and wear resistance, supporting longer service life on pilot features. PS4 is provided as an alternative steel choice per the available variant list, enabling designers to select based on their tooling usage and procurement preference.

  • Wear vs. toughness trade-off: Hardened steels improve abrasion resistance at the tapered tip/ball lock area, but overly aggressive hardness can reduce impact toughness. Choose the variant that matches your cycle load and alignment severity.
  • Heat treatment state: The product description indicates hardened wear resistance for tooling use, implying a heat-treated condition suitable for repeated press cycles.
  • Manufacturing process: These pilot punches are machined to the specified inch shank diameter and point/length geometry, then heat-treated to achieve the hardened wear surface needed for consistent locating.
📐Sizing & Selection Guide+

Select dimensions by matching the shank diameter D and the point/length configuration to your mold’s pilot bushings and locating seats. The shank diameter range is specified as D = 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), or 1.0000" (100), so pick the diameter that matches the receiving pilot station clearance and guide bore.

  • Choose the correct length band: Standard point length & L is coded 250–600 or 250–700 (with corresponding B/L listings).
  • When using fixed configuration: The fixed “D Point Length B & L” option is specified as 275–700, which you should align with your required projected working length in the mold.
  • Match geometry to ball lock engagement: Ensure your assembly supports the ball lock pilot function and that the selected point length provides proper engagement without bottoming.

Dimension P is given as 0.083 ~ 0.749 in; use it to confirm the locating projection/step relative to the mating die components. If your system has tight clearance requirements, verify fit by measuring the mating bore and using the closest available coded length.

Frequently Asked Questions

Which shank diameter D options are available for these inch ball lock pilot punches, and how do I match them to my pilot station bore?+

Available D (shank diameter) options are 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), and 1.0000" (100). Select the D size that matches the receiving guide/pilot opening in your die set to maintain stable guided entry and consistent ball lock engagement. When ordering, keep the coded length (L / B) consistent with your projected engagement requirement so the geometry doesn’t bottom out.

What point length and L ranges can I select for the tapered tip light-duty version, and what does the ‘fixed’ configuration imply?+

The Standard Point Length & L is specified as coded inch 250–600 or 250–700. The B (point length) & L listing follows 250–600 or 250–700, and there is an additional C option of 250–600 / 275–700. A fixed configuration is also listed for D Point Length B & L = 275–700, meaning the build geometry is constrained to that range—use it when your die design requires that specific working length band.

Should I choose M2 or PS4 for locating and wear resistance at the tapered tip—what key differences are relevant?+

This series is offered in M2 or PS4 as the available material variants. The description indicates hardened wear resistance for tooling use; in practice, both options are selected to protect the locating interface under repeated press cycles. M2 is typically chosen for a strong balance of hardness and wear performance, while PS4 provides an alternate steel selection within the same light-duty pilot-punch application scope.

How do the tapered tip geometry and light-duty design affect alignment during die closing?+

The tapered nose is intended to improve guided entry and reduce start-up force, which helps maintain stable alignment during press cycles. In light-duty progressive/transfer die applications, this reduces the risk of misalignment caused by high insertion shock. To take full advantage, pair the correct D diameter with a compatible point length so the taper initiates guidance before ball lock engagement fully seats.

How can I use dimension P (0.083–0.749 in) when verifying my final pilot engagement height?+

Dimension P is specified as 0.083 ~ 0.749 in, which can be used to confirm the locating projection/step relative to your mating die components. In die design, this dimension helps ensure the pilot punch engages the ball lock properly and that the point length (coded L/B) provides the required working engagement without bottoming. When selecting a coded length (250–600 / 250–700 / 275–700), verify the resulting stack-up against your pilot station geometry using P as the reference.
