Point Larger than Shank Ball Lock Punches - Heavy Duty, Metric

These heavy duty metric ball lock punches are used in injection mold tooling and precision press stations where repeatable punch retention and stable positioning are critical. In ball-lock retention systems, the larger point than shank helps self-locate at the start of the cycle, reducing the risk of misalignment before full forming or part ejection begins.

• Automotive connector and terminal molds: Suitable for multi-cavity tooling that cycles continuously; the geometry supports reliable engagement of ball locks, while the XCN coating helps maintain performance under abrasive wear from repeated contact.
• Electronics and thin-wall components: Used where precise punching of features is required; the larger point improves guidance through die/punch interfaces, supporting consistent forming depth and cleaner ejection.
• Appliance housings and brackets: Ideal for heavy duty metric setups with longer punch lengths; consistent retention supports dependable part removal and reduces downtime from wear-induced fit change.

The provided product specifications describe the tip shape and dimensional ranges, but no steel grade, hardness (HRC), or heat treatment state is listed. As a result, heat-treat and hardness claims (e.g., quenched & tempered, nitrided, target HRC) cannot be stated from the given data.

• Surface performance: The XCN coating is included to help reduce wear during repetitive pressing cycles. This supports stable contact behavior and helps limit dimensional drift over time.
• Trade-offs: For ball lock punches, wear resistance and long-term positional stability are often balanced against toughness requirements; use the manufacturer’s material datasheet to confirm toughness/impact performance if your process involves shock loading.
• Material comparison note: If alternate steel grades are available in your sourcing package, compare based on the requested hardness/toughness targets and your abrasive vs. adhesive wear conditions.

Select the punch by matching the shank diameter (D), overall length (L), and the point length (L1) to your mold cavity/core interface and ball-lock retention design. This variant is defined for L1 = 19–30 mm and L = 80–100 mm, with selectable tip shape options (H, J, K, L, N, O, R, V, X, Y, Z).

• Step 1: Choose shank diameter D (mm): Available D values are 13, 16, 20, 25, 32, 40. Ensure the punch shank fits the corresponding ball-lock pocket/bore design.
• Step 2: Match point length L1: Use the required working engagement length within the tool; confirm enough clearance for ball-lock travel.
• Step 3: Confirm P and W dimensions: P is provided in ranges by D (e.g., 13.1–32, 16.1–38, 20.1–40, 25.1–44, 32.1–50, 40.1–56), and W is 1.57–34.73. R is listed as 0.2.

Verify your drawing-level clearance and retention fit against the mating holder specifications; the contact interface is governed by D, the ball-lock seat, and the point geometry (larger than shank) for stable initial alignment.
