Ball Lock Pilot Punches Round Tip Heavy Duty XVP Coating

Ball lock pilot punches with a round, heavy-duty tip are used in die try-outs and later progressive/transfer mold production to establish stable punch-to-die alignment. The ball-lock locating concept supports repeatable seating, reducing shift risk when the tool cycles at speed and under forming load.

• Progressive automotive connector/terminal tooling: Round-point guidance helps maintain consistent registration across stations, while the XVP surface treatment improves durability against wear from frequent alignment engagement.
• High-cycle metal stamping dies: The heavy-duty point geometry supports locating performance under higher contact stress during in-die feed and part knock-out phases.
• General die setup and transfer systems: Use these pilots for reliable initial alignment of die sets and transfer mechanisms, where repeatability directly impacts part dimensional stability.

The M2/PS4 material options and the XVP coating make this variant suitable when you need dependable positioning plus improved surface life during repeated try-out and production cycles.

This pilot punch is offered in M2 and PS4 materials, selected to balance wear resistance and toughness for die alignment service. M2 is an AISI M2 equivalent high-speed steel grade, typically chosen for its excellent abrasion resistance and stable hardness under intermittent loading. PS4 is commonly specified for tooling applications requiring strong wear performance with good toughness trade-offs (material property specifics depend on supplier processing).

For heavy-duty punch-to-die guidance, the design relies on a hard, wear-resistant surface. The XVP coating further improves surface durability by enhancing resistance to scuffing and adhesive wear during frequent ball-lock engagement. Expect hardness to be optimized via standard tooling heat treatment (the punch body is produced in a hardened state appropriate for pilot service), with the coating providing additional life at the contact interface.

• M2: Higher wear/abrasion resistance typical of high-speed steel applications; may show lower toughness than lower-alloy alternatives at equal hardness.
• PS4: Often selected when toughness-at-wear needs a different balance versus M2 for similar alignment duty.

Select dimensions to match your mold’s core/cavity locating requirements and the intended engagement depth. This series provides D (shank dia.) in the range 10 ~ 40 mm and multiple point length L1 options: 12 ~ 21, 15 ~ 27, or 21 ~ 32 mm.

Then choose total L (punch length) from the available ranges: 65 ~ 112, 65 ~ 127, 73 ~ 127, 92 ~ 127, or 112 ~ 127 mm, depending on your press stroke, die thickness, and required pilot protrusion through the die set. The P dimension is specified as 1.45 ~ 29.95 mm, and should be matched to your locating geometry/ball-lock features.

• Verify that D and L provide clearance for the die block and guide system while ensuring full seating of the ball-lock during alignment.
• Account for tooling tolerances in the pilot bore/landing to maintain repeatable fit; follow your die manufacturer’s standard clearance for hardened pilot components.
• All listed size ranges are configurable by selection; choose the combination that satisfies cavity/core engagement length without bottoming during try-out.
