Ball Lock Pilot Punches Round Tip Heavy Duty Inch XCD Coatin

Ball lock pilot punches are used in progressive die sets to establish precise, repeatable part positioning as the strip advances. The round tip and ball-lock geometry maintain consistent engagement between the punch and mating tooling, helping stabilize punch-to-cavity alignment under production vibration.

• Automotive and industrial progressive forming: Select this heavy-duty variant when you need reliable locating across repeated stations. The XCD coating variant is suited for long cycles where tip wear would otherwise degrade location accuracy.
• Connector and bracket stamping dies: Use where the pilot must guide the stock reliably through tight tolerances. The ball-lock engagement supports repeatable guidance, improving throughput consistency.
• General purpose progressive tooling: Works well for die sets that require inch-coded length options so the locating stroke matches the cavity/core relationship.

With available inch coded lengths (250–700) and inch shank diameter coverage, this configuration can be matched to your station stack-up to reduce misalignment risk.

This series is available in M2 and PS4, allowing selection based on wear and toughness requirements. M2 (high-speed steel) is commonly chosen for balanced wear resistance and toughness, making it suitable for demanding locating surfaces that experience repeated contact.

• M2: High wear resistance with good toughness; typically quenched and tempered to reach a practical cutting/punching hardness range (exact HRC not provided in the supplied data).
• PS4: Often selected as an alternative alloy steel option for tooling applications where wear behavior and cost/performance balance are priorities (exact hardness state not provided in the supplied data).

Manufacturing is typically via precision machining of the shank and tip, followed by surface finishing to ensure concentric locating. For this product variant, the XCD coating is intended to improve wear resistance at the ball/round tip contact region, helping maintain guidance over longer runs; this can shift performance toward wear durability with a potential trade-off in sensitivity to coating damage if misaligned or overloaded.

Correct selection starts with the shank diameter D and the inch-coded point length options. Choose a shank diameter within the available range of D = 37–125 (in), then match the point length code to your die station stack-up requirements.

• Length code selection: Available standard point length & L ranges include 250–600, 250–700, 275–700, and 300–700 (inch-coded).
• Point length B & L / C / D variants: Some configurations list additional combinations (e.g., 300–700 and 300–700 shown for C and D-coded ranges). Use the code that corresponds to the geometry variant you are sourcing.
• Engagement and clearance: Ensure the selected coded length provides sufficient engagement for ball-lock contact without bottoming against the mating surface.

For fit, consider the listed P dimension = 0.061–0.999 (in) when your die design specifies a pilot-to-bushing interface or clearance-sensitive location feature. If your system uses tight fits, verify compatibility with your mating bushing/pocket dimensions and the toolmaker’s required tolerance stack for progressive station alignment.
