Inch Point Larger than Shank Ball Lock Ejector Punches XVP Coating

This inch point larger than shank ball-lock ejector punch variant is used in die tooling where consistent retention and controlled ejection are required across high production cycles.

• Automotive and industrial stamping dies: The larger tip-to-shank geometry supports stable ball-lock seating during repeated die close/open actions, helping reduce positioning drift and maintaining predictable ejector travel under load.
• Heavy-duty forming and progressive dies: XVP coating is selected to improve surface wear behavior, supporting longer punch service intervals in abrasive, scale-prone environments.
• Die sets requiring standardized inch builds: The inch configuration provides compatibility with common die-cavity/core tooling conventions, simplifying fit-up in established press tooling.

Overall, this design is suited when you need secure ball-lock retention plus enhanced durability at the point contact zone for long-running die work.

The provided specifications for this series focus on geometry (tip shape, shank diameter, length codes) and the XVP coating, but no base steel grade or hardness value is specified in the product data.

For material selection at the engineering level, treat this as a coated ejector punch where performance is driven by the XVP surface treatment: it is intended to improve wear resistance at the point-contact and sliding interfaces, which can reduce spalling and maintain ejection stability over time.

• Hardness/toughness trade-off: Coatings typically enhance wear performance; ensure the underlying punch steel selection meets impact and bending requirements for your ejector loading, since coating alone does not guarantee toughness.
• Heat treatment: The data does not list a specific quench/temper, nitriding, or pre-hardened condition, so confirm the base metal condition with your quotation for definitive hardness (HRC) and tempered microstructure targets.

If multiple material options are offered for this series, compare them by hardness (HRC), coating adhesion compatibility, and expected abrasive load life.

To select the correct dimensions, match the ejector geometry to your die design’s ball-lock and guidance requirements using the series’ specified ranges.

• Choose tip shape: Select one of the allowed tip shapes H, J, K, L, N, O, R, V, X, Y, Z based on the contact profile needed for your cavity/core and ejection clearance.
• Shank diameter (D): Order within 37 ~ 125 in (as listed for this series). Ensure the die's ball-lock bore and retaining features are designed to accept this shank diameter.
• Length (L coded inch): Use 250 ～ 450 or 275 ～ 450 coded inch options, depending on required protrusion and die layout thickness.
• Point/interface dimensions: Verify P (0.376 ~ 1.251), W (0.062 ~ 1.083), and R (0.007 ~ 1 depending on the listed range set) to ensure correct tip seating and part-release behavior.

Because tolerances and fits are not provided in the data, use your die set tolerances to confirm allowance for insertion and ball-lock engagement; request the specified dimensional tolerances with the quote for final verification.
