Ball Lock Ejector Punches Light Duty Inch X-Shape XCD Coating

Ball lock ejector punches with an X-shape tip are used to hold punch location securely while parts are blanked and ejected in light-duty inch tooling. They are especially effective in progressive and transfer dies where repeatable punch seating impacts stroke consistency.

• Progressive die ejector stations: The ball-lock retention helps maintain stable punch position during indexing, supporting consistent ejection after multiple cycles.
• Automotive/industrial connector blanking: For precision blanking work that benefits from controlled wear at the working edge, the XCD coating supports longer service intervals in typical intermittent shock loading.
• General press blanking fixtures: The inch shank format improves compatibility with standard ejector assemblies and indexing interfaces.

This variant’s drilled shank support and XCD coating are suited to applications that prioritize reliable blanking performance and predictable ejector behavior.

These ball lock ejector punches are offered in M2 or PS4 material options, selected to balance hardness, wear resistance, and toughness for different blanking profiles. M2 (AISI M2 equivalent high-speed steel) is typically chosen for higher wear resistance at the punch tip, particularly when the tool sees repeated abrasive contact.

• M2: Commonly heat treated to achieve high hardness (often around the mid–high HRC range for HSS grades), improving edge retention under sustained contact; toughness is generally lower than some lower-alloy steels.
• PS4: Selected when improved toughness characteristics are needed for stable performance in lighter press conditions and for certain wear environments.

In both options, the XCD coating is used to reduce surface wear at the working region, supporting longer service intervals compared with uncoated punches. Exact hardness and heat-treatment state depend on the configured material variant.

To select the correct punch, start with the shank diameter (D) in the range 25 ~ 100 in and match it to your ejector guide and punch holder interface. Next, choose the standard point length L using the coded inch ranges: 200 ~ 400, 200 ~ 500, 200 ~ 600, or 225 ~ 600, depending on the required tip reach and stack-up.

• Point length B & L (coded inch): options include 225 ~ 400, 225 ~ 500, and 225 ~ 600 (variant-specific).
• Fixed configuration: if configured as fixed, B & L is 250 ~ 600, which simplifies selection when your die geometry matches that range.
• Tip geometry: select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to align with your blanking contact requirements.

For dimensional fit, ensure the selected D and L clear the die cavity/core stack-up and that the ball-lock retention can seat fully without interference. Coating and tip profile can affect effective wear behavior, so size to the tool’s functional dimensions rather than worn targets.
