Ball Lock Regular Punches Heavy Duty Inch XNAP Coating

Ball lock regular punches with an X-shaped tip are commonly used in progressive die sets where stable blanking and controlled ejection are critical. The X-shaped working geometry helps maintain alignment during feeding and forming, which supports consistent punch seating and part release across production cycles.

• Progressive blanking of sheet metal: Suitable for heavy-duty inch tooling where the punch must withstand repeated impacts while preserving dimensional consistency. The XNAP coating improves surface wear performance for long runs.
• Automotive and industrial connector housings: Used in station layouts that combine piercing and blanking operations, benefiting from reliable ejection timing and reduced tip wear that can affect part edge quality.
• High-throughput appliance or chassis components: Ideal when cycle rate and strip handling demand repeatable punch alignment; the tip shape supports steady performance under load.

For these applications, this variant’s inch-ready configuration and XNAP-coated, heavy-duty construction help maintain productivity while minimizing maintenance intervals.

This ball lock punch line is offered in M2 and PS4 material options, supporting different durability requirements for inch tooling.

• M2 (AISI M2 equivalent) is a high-speed steel known for strong wear resistance and good toughness balance in punching/blanking service.
• PS4 provides an alternative steel choice for die-makers seeking a different compromise between edge retention and toughness under repetitive loads.

Both options are typically manufactured as die-ready punch blanks and then machined to the specified tip shape (including the X-shaped tip variant) and shank dimensions. Heat treatment is performed to reach the required cutting and wear performance; final hardness is set to deliver stable resistance to abrasion while maintaining sufficient toughness to avoid premature chipping at the working edge.

Use the material choice to tune the trade-off between maximum wear life and impact toughness for your expected cycle count and strip handling conditions.

Select the correct punch size by matching your die station requirements to the provided D (shank dia.), L (point length), and tip geometry.

• Shank diameter (D): Choose from 37 ~ 125 in (per the product’s specified inch range) to fit the ball-lock system and guide hardware in your progressive die.
• Point length / L: Use the coded-inch ranges: 250 ~ 600, 250 ~ 700, 275 ~ 700, or 300 ~ 700, depending on your strip thickness and required working penetration.
• B / C / D point length variants: The same coded ranges appear for B & L and C & L, with additional options shown for D (point length) at 275 ~ 700 and 300 ~ 700.

Dimension checks should also account for dimensional controls: P is specified as 0.05 ~ 1, W as 0.05 ~ 0.5, and R as 0.007 (per the data). When selecting, confirm that the punch-to-die fit and alignment tolerances in your ball-lock holder match the chosen shank diameter.
