Ball Lock Ejector Punches - Heavy Duty Inch X-Shaped Tip

These heavy-duty ball lock ejector punches are used in press tooling where consistent punch return and repeatable contact geometry are required. The ball-lock style helps maintain a stable fit within punch & die assemblies, reducing variability across cycles.

• Automotive and industrial stamping: X-shaped tips support consistent force transfer during ejection, helping maintain predictable clearance and part release over long production runs.
• Metal forming, trimming, and blanking: The hardened steel build is suited for wear-focused service, where tip edges must resist abrasive and impact wear while sustaining return performance.
• Multi-up tooling stacks: Select the coded inch point length options (250–600) to match typical tooling stack heights and maintain proper engagement without under- or over-travel.

This punch series supports two material selections: M2 and PS4. M2 is typically chosen for its strong wear resistance in cutting and punching environments, while PS4 is selected when a balance of durability and toughness is preferred for press tooling service.

• Heat treatment state: Hardened steel construction is specified for long service life in punch & die assemblies.
• Hardness and wear vs. toughness trade-off: Hardened tooling steel provides improved abrasion and edge wear resistance, with performance dependent on the specific heat-treatment condition used by the manufacturer for M2 or PS4.
• Tip compatibility: Pair the chosen material with the X-shaped tip geometry to maintain consistent contact during ejection and reduce wear-driven geometry drift.

If you share your press load range and part material (steel/aluminum/etc.), we can recommend whether M2 or PS4 aligns better with your wear and toughness requirements.

Selection starts with matching the shank diameter D to your tooling system and guidance hardware. This series covers D = 37–125 in, so choose the value that fits your ejector support bore and ensures stable alignment during ejection.

• Choose the tip style: The available tip forms include H, J, K, L, N, O, R, V, X, Y, Z. For the heavy-duty inch X-shaped tip variant, select the X geometry.
• Select coded point length: Standard point length and overall L are offered in coded inch ranges such as 250–500, 250–600, 275–600, and 300–600. Additional coded ranges are also provided for B & L, and point length options are listed across B and C variants, as well as a D point length set up to 250–600 / 275–600 / 300–600.
• Fine geometry checks: Verify P = 0.062–1 in and W = 0.062–0.5 in against your cavity/core clearance requirements.

For fit, ensure the shank diameter and guidance interface provide the intended clearance to prevent binding during ejection; use the coded length to avoid bottoming and maintain correct engagement depth.
