Ball Lock Regular Punches Heavy Duty

These heavy-duty ball lock punches are used in inch-based punch tooling where consistent blanking and dependable part stripping are critical. In automotive connector and bracket press operations, the stable ball-lock retention helps maintain punch position in the holder during high-cycle runs, supporting repeatable blank size and predictable strip-off behavior.

They are also suitable for electronics and appliance components that require accurate blanking of thin-to-medium gauge sheet. The XCN coating options are selected to improve wear resistance under abrasive press loads, helping reduce dimensional drift over regrinds.

• Automotive connector molds/tooling: stable retention in holders for consistent stripping and blanking.
• Electronics/appliance press operations: coating-enhanced wear resistance for long-running cycles.
• High-volume forming lines: standardized punch design supports repeatable setups and regrind workflows.

This punch series is offered in M2 and PS4 steel options, with tip shapes available in H/J/K/L/N/O/R/V/X/Y/Z. M2 is typically used when high wear resistance and cutting edge durability are priorities, while PS4 is selected when a balance of toughness and wear performance is required for press production.

For robust punch tooling, the steel is produced and heat-treated for service hardness. Depending on the selected grade and coating (such as XCN options), the manufacturing route commonly includes a quench-and-temper or equivalent hardening process to achieve the required hardness for blanking while maintaining toughness to resist chipping under impact loads.

• M2: high hardness potential; strong wear resistance for demanding cycles.
• PS4: toughness-focused option compared to very high-hardness grades.
• XCN coating option: supports wear life and helps stabilize performance during repeated regrinds.

Select dimensions by matching the punch shank, point length, and point shape to the die cavity/core geometry and strip conditions. Start with the D (Shank dia.) range of 37 ~ 125 in to ensure proper fit within your ball lock punch holder. Confirm that your holder’s ball-lock interface is compatible with the chosen shank diameter and tip style.

Next, choose the point length based on your required penetration and blanking depth. Supported standard point length & L coded inch ranges include 250–600, 250–700, 275–700, and 300–700. For long-hole/strip profiles, verify whether your setup requires the narrower options tied to specific D ranges (for example, D point length B & L: 275–700 or 300–700 as listed).

• P dimension: 0.05 ~ 1 in
• W dimension: 0.05 ~ 0.5 in
• R dimension: 0.007 in (fixed range stated)

Use the listed ranges to map directly to cavity/core working dimensions; where regrinding is expected, standardize the initial length selection and maintain consistent regrind allowances to preserve fit and stripping stability.
