M2 Steel Ball Lock Regular Punches - Light Duty

Ball lock punches are used inside injection mold tooling and die sets to drive consistent ejection of small parts and sprue/riser remnants. The light-duty variant is well suited for metric die applications where repeatable punch-to-die retention and stable alignment under cycling are required.

• Automotive connector and terminal molds: Apply these punches to eject thin-wall inserts or localized features. The ball-lock head helps maintain engagement during repeated press cycles, reducing misalignment that can lead to scuffing or incomplete ejection.
• Electronics enclosures and light housings: Use for ejection pins/punches where loads are moderate and precise positioning matters. The ground/precision fit supports stable seating in the tool assembly for reliable part removal.
• Medical device housings (low-load features): Suitable where consistent ejection force is needed without heavy wear demands. The hardened M2-family construction supports wear resistance for dependable cycling.

Tip shape options (H, J, K, L, N, O, R, V, X, Y, Z) let you match the punch contact geometry to the part feature being ejected.

These punches are offered in multiple tool steels, including M2 (HSS), A2, and PS4, enabling selection based on wear and toughness needs. For the M2 option, the grade is commonly treated as an AISI M2 equivalent, chosen for strong wear resistance in light-to-moderate duty ejection and die operations.

• M2 / AISI M2: Typically heat treated to a hardened condition to improve wear resistance; trade-offs include reduced toughness compared with lower-alloy tool steels under impact.
• A2: Often selected when a balance of toughness and wear resistance is preferred for less aggressive wear scenarios.
• PS4: Used where the application calls for different wear/finish characteristics versus M2/A2.

Exact hardness (HRC) and the specific heat-treatment recipe (e.g., quenched & tempered vs. nitrided) are not provided in the available specifications, so confirm with the supplied datasheet for final qualification.

Select the correct ball lock regular punch by matching the shank diameter (D), overall length (L), and point length (L1) to your die cavity/core geometry and ejection travel. In this series, D ranges from 6 to 38 mm, with multiple available L1 ranges (10–13, 10–19, 13–25, 19–30 mm) and L ranges (63–100, 63–100, 71–100, 80–100 mm) depending on the configuration.

• Match D to the guide/bushing fit: Ensure the die/pin hole size accommodates the shank diameter and maintains stable ball-lock retention during cycles.
• Set L for safe clearance: Verify the overall length provides enough support while maintaining clearance to avoid bottoming in the open/closed position.
• Control contact depth with L1: Use the point length to reach the ejection interface without over-penetration.

Tip geometry is configurable via tip shapes (H, J, K, L, N, O, R, V, X, Y, Z), and tip contact size is influenced by P (1.4–12 mm), W (1.4–14 mm), and R (0.2 mm). Tolerance values are not listed, so rely on the manufacturer’s dimension drawing for final fit and assembly verification.
