M2 Steel Ball Lock Regular Punches - X-Shaped Tip

These ball-lock punches with an X-shaped tip are used in precision ejection systems where repeatable retention and controlled release are critical. In metric progressive and transfer dies, the tip geometry helps maintain punch-to-matrix alignment during high-cycle press operation, supporting stable part positioning through each stroke.

They are also suited for heavy-duty automotive connector and terminal tooling, where long run times demand wear-stable punch faces and consistent ball-lock engagement. The M2 steel variant’s wear resistance supports dependable ejection under intermittent shock loading typical of metal forming and punching.

When paired with ball-lock posts and springs, the regular punch body provides predictable contact behavior, reducing the risk of sticking or uneven ejection that can occur when tip alignment varies. Choose the X-shaped tip variant for applications emphasizing alignment control and reliable ejection repeatability.

The primary offering uses M2 steel, a high-speed steel known for strong wear resistance and good toughness for punch and die contact surfaces. In this family, an alternate PS4 material option is also available to support different wear/toughness needs depending on your load and cycle profile.

• M2: typically used in a hardened condition to balance wear resistance with sufficient toughness; as a benchmark, M2 is commonly delivered in the range of ~60–65 HRC after proper heat treatment.
• Tip hardening approach: punches are generally manufactured with a hardened state (commonly quenched and tempered for HSS variants), then finish-machined to final dimensions for stable tip geometry.

Trade-off: higher hardness improves wear life but can reduce impact toughness if over-hardened or if part-to-part load spikes are severe—select the material variant that matches your shock and abrasion balance.

Selection starts with matching the shank diameter D (10 ~ 40 mm) to the ball-lock punch mounting features in your die set. Next, choose a point length L1 that fits within the available engagement depth: available ranges are 10–19 mm, 13–25 mm, or 19–30 mm.

• Confirm overall L (length) to clear carriers and guide components: options are 63–125 mm, 71–125 mm, or 80–125 mm.
• Use P (1.5 ~ 12 mm) and W (1.5 ~ 14 mm) to align the tip and contact geometry with your die pocket and retention ball path.

Because this is a precision punch component, verify dimensional fit against your ball-lock system design, including clearance around the ball pocket and any guide features. If your die requires tight repeatability, treat the final machined dimensions as fixed and specify the desired series in your cavity/core drawings so tolerances remain consistent across the punch set.
