M2 Steel Ball Lock Ejector Punches Light Duty XCD Coating

This ball-lock ejector punch is used in injection/die tooling where stable part release depends on repeatable ball engagement. The light-duty configuration and compact shank range (D = 6–38 mm) make it well-suited for smaller ejector assemblies in metal forming and press operations.

In automotive or appliance metal forming, the X-shaped tip geometry helps maintain consistent contact with the workpiece during short-run cycles. The XCD surface protection supports reliable ball-lock operation by improving wear behavior at the contact zone, reducing the risk of sticking or uneven ejection.

For light-duty die inserts and metric die sets, the available tip shapes (including X and other variants) allow designers to tune tip-to-part contact without changing the ejector concept. Pairing the M2 construction with the XCD-coated interface makes this variant practical when you need dependable ejection while keeping maintenance intervals reasonable.

The base steel for this variant is M2 (high-speed steel). In the same M2 family, its typical role in ejector tooling is to provide high hardness and good wear resistance under intermittent sliding/contact at the punch tip and ball-lock interface.

This product is specified with an XCD coating to further enhance surface durability in demanding cycles. The intent is to improve resistance to abrasive wear and micro-surface damage at the tip contact area, supporting consistent engagement.

• Heat-treatment state: the description indicates “hardened construction,” meaning the steel is manufactured for service hardness suitable for ejector applications.
• Wear vs. toughness trade-off: higher hardness improves wear life but can reduce impact tolerance; the light-duty design helps balance this by using geometry appropriate for lighter loads.

An alternative material option is PS4. Select between M2 and PS4 based on your hardness/wear needs and the expected contact conditions, while keeping the XCD-coated surface protection for consistent interface performance.

Start by matching the ejector punch shank diameter to your ejector bushing or bore: this series supports D = 6–38 mm. Choose the length (L) that fits your die stack-up and allows proper clearance and retention—available L ranges include 63–100 mm, 71–100 mm, and 80–100 mm depending on the configuration.

Next, select the point/tip geometry and point depth. The Point Length (L1) is offered in 10–13, 10–19, 13–25, and 19–30 mm, and the contact geometry can be configured by Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z). For X-shaped tip applications, confirm that the effective tip reach matches the required ball-lock engagement and part-release travel.

• Profile dimensions: P = 1.4–12 mm, W = 1.4–14 mm, and R = 0.2 mm are configuration-dependent—ensure compatibility with the receiving pocket and contact area.
• Tolerance/fit: maintain the designed clearance between shank and guide/bore for smooth ejection; use the specified D to preserve the intended fit class for die machining.
