Ball Lock Pilot Punches Tapered Tip Heavy Duty Inch

These heavy-duty ball-lock pilot punches with a tapered tip are used to establish repeatable alignment during injection mold setup, especially where accurate location of inserts, cores, or side actions is critical.

• Automotive connector and bracket molding: the tapered entry helps start centering reliably at every cycle, supporting stable lock-in for multi-part assemblies and press-in features.
• Electronics housings and module inserts: the ball-lock design provides consistent initial positioning, reducing drift during high-throughput forming and post-mold assembly operations.
• Industrial appliance and enclosure tooling: the inch heavy-duty construction is suited for robust die/mold systems that see frequent maintenance and varied material flow pressures.

The M2-based variant combined with the XNM coating supports long-term wear resistance, helping maintain dimensional stability at the pilot interface where misalignment directly impacts part quality.

This series is available in M2 (high-speed steel) and PS4. The meta description specifies M2 steel as the primary variant for durable locating; M2 is commonly selected for a balance of hardness, wear resistance, and toughness in tooling contact zones.

• M2: typically hardened to a high hardness level (often in the ~HRC range used for cutting tools) to resist abrasion at the tapered entry and ball-lock seating surface.
• XNM coating: enhances wear resistance at the pilot contact, helping reduce material galling and surface degradation during production.
• PS4 (alternative): offered as a substitute material option for projects that require a different supply/fit strategy while retaining the pilot’s locating function.

For best performance, follow standard HSS practice for heat treatment (quench and temper after hardening) before finishing; in service, the coating and surface geometry determine wear rate more than bulk toughness alone.

Select the pilot punch based on the mold’s pilot hole diameter and the required point length for full seating. Match the shank diameter D within the provided range: 37 to 125 in (as listed for D). Confirm the receiving components’ pocket/hole geometry can accommodate the shank without interference.

• Point length (L) and coded options: available in groups 250–600, 250–700, 275–700, and 300–700 (inch coded lengths). Choose the length that reaches the ball-lock seating depth before full clamp.
• B and C length codes: B/C are also offered in the same coded ranges (e.g., 250–600 through 300–700), depending on configuration.
• P dimension: use 0.083 to 0.999 in per your locating tolerance stack and ball-lock engagement requirement.

Because these are locating features, keep tolerance and fit tight at the contact surfaces; if your mold uses standard pilot hole tolerances, verify clearance specifically around the tapered tip before final tryout.
