Ball Lock Pilot Punches - Tapered Tip, Heavy Duty, XCD Coati

Ball lock pilot punches with a tapered tip are used to establish reliable die-to-die alignment in progressive stamping and transfer tooling, especially during start-up and at high cycling rates. The tapered geometry improves initial locating accuracy, helping prevent skew as the press approaches full transfer speed.

• Progressive die alignment: Use the inch shank diameter and coded point lengths to match cavity spacing and maintain consistent feed indexing between stations.
• Automotive connector or bracket stamping: The heavy-duty ball lock pilot helps stabilize registration under vibration and repeated load cycles, while the XCD coating supports long-term wear resistance at the locating interface.
• Tooling plates and press applications: Pair the required point length range with press-style die mounting holes to ensure repeatable pilot engagement and reduce misalignment risk.

This variant is suited for applications where tight alignment and locating repeatability are required, and where surface wear at the pilot contact point can degrade locating performance.

These ball lock pilot punches are available in M2 or PS4 steel, selected for tooling durability under repetitive locating loads. M2 is a high-speed steel family commonly chosen for its balance of wear resistance and toughness; PS4 provides an alternative steel option when a different durability/toughness balance is preferred by the user’s process.

• Wear performance: With the XCD coating, surface wear at the tapered locating point is reduced to help maintain dimensional locating consistency over extended cycles.
• Hardness & trade-offs: The specific hardness level (HRC) and exact heat-treatment schedule are typically set to achieve high wear resistance at the pilot tip while retaining enough toughness to resist chipping under impact loading.
• Heat treatment state: These steels are generally supplied in a prepared condition appropriate for hardened tooling use (exact specification not provided in the input data).

For the highest locating interface longevity, match steel choice to expected stamping severity while relying on the XCD coating to reduce surface wear.

Select the correct punch dimensions by matching your die set’s locating features to the available ranges for shank diameter and point/length codes.

• Shank diameter (D): Choose from 37 ~ 125 in to fit the pilot receiving/bushing hole size in your tooling.
• Point length and overall length codes: Standard point length & L are offered in coded inch ranges: 250 ～ 600, 250 ～ 700, 275 ～ 700, or 300 ～ 700. Use the same code family for point length B & L (B) and length (L) where applicable.
• Additional reduced set (D & B/L specific): Some configurations list point lengths 275 ～ 700 and 300 ～ 700.

Confirm that the pilot engagement length provides sufficient contact during press travel without bottoming. Where fit is critical, use the stamped die’s locating hole/bushing tolerance targets to ensure stable ball lock retention and consistent repeatability across assemblies.
