DIN Standard Ball Lock Pilot Punches Tapered Tip (XNA Coatin

Ball lock pilot punches with a tapered tip are used in injection mold and die tooling where repeatable part localization is critical but cutting forces are relatively light. In two-plate and progressive die sets, the tapered point helps initiate alignment at the start of stroke, improving indexing stability and reducing setup variation when switching production lots.

They are also well-suited for automotive and electronics connector housings that require consistent cavity-to-core registration for small features and tight cosmetic tolerances. The DIN-standard build supports predictable punch alignment, while the hardened body and XNA coating help maintain guidance wear characteristics over repeated cycles.

For consumer device and appliance mold components with frequent tool maintenance, the tapered geometry enables easier re-centering during refurbishment. Select the variant with the required shank diameter and point length to match your pilot bushing/locating hole system and keep the ball-lock locating function stable.

This DIN-standard pilot punch is hardened and finished with an XNA coating to improve surface durability under sliding guidance loads. The hardened steel body provides wear resistance for light-duty locating, while the coating supports stable punch performance by reducing friction and limiting point wear during repeated press cycles.

Key material behavior for this application:

• Wear resistance: enhanced by the XNA coating, supporting consistent pilot guidance over time.
• Toughness trade-off: hardened tool steels offer higher hardness and abrasion resistance, but must be sized appropriately to avoid tip chipping under misalignment.
• Heat treatment state: described as hardened for service locating; the exact HRC and quench & temper parameters are not specified in the provided data.

If you compare coating options, XNA is typically chosen when you need stable light-duty locating with improved wear life versus uncoated or less durable surface finishes. Always validate coating compatibility for your expected lubricants and cycle rate.

Correct selection starts with matching the shank diameter (D) and overall geometry to your mold’s locating system. Choose D = 10 ~ 38 mm so the pilot punch seats properly in the corresponding ball-lock pocket/guide feature without excessive clearance.

Then select the guidance length features based on your shut height and stack-up:

• Point length (L1): available as 19 ~ 72, 19 ~ 102, 25 ~ 112, 30 ~ 112 mm (choose the range that reaches the intended alignment start depth).
• Overall length (L): options include 71 ~ 110, 71 ~ 140, 71 ~ 150, 80 ~ 150 mm to ensure the punch remains engaged through the full stroke without bottoming.

Finally, confirm the P dimension = 1.45 ~ 30 mm, which affects the locating geometry and engagement profile. Use engineering drawings to align cavity/core registration requirements with the pilot’s contact length; tolerances depend on your die set and locating hole specs, so maintain the designed clearance to prevent binding and to preserve repeatability.
