Ball Lock Regular Punches Heavy Duty Inch

These heavy-duty ball lock punches are used in die set tooling for high-cycle punching operations where long-term dimensional stability and repeatable fit in the punch holder are critical.

• Progressive and transfer dies: The ball lock geometry provides secure retention during repeated strikes, helping maintain punching alignment and reducing the risk of punch drift.
• Inch-system die components for fabrication: Choose the inch variants with the specified shank diameter range and coded point lengths to match existing die-set standards and maintain consistent stack-up.
• Wear-prone punching tasks: The XNA coating finish is suited for applications with frequent contact and abrasion, improving surface durability and supporting more consistent output over production runs.

Because this variant is specified as heavy duty in an inch configuration and is available with materials including M2 and PS4, it fits both demanding production environments and die sets that require stable retention and controlled wear.

This punch series is offered in two material options: M2 and PS4. The M2 option (a high-speed steel, commonly used where tool-life and hardness are prioritized) is typically selected for excellent wear resistance under repeated impact and friction.

The PS4 option is chosen when a different balance of toughness and wear performance is required for specific die-set conditions. Exact hardness and heat-treatment state are not provided in the supplied data, so the final HRC value should be confirmed with the manufacturer documentation for the selected material.

• XNA coating finish: complements both steel options by reducing friction and abrasion during repeated strikes.
• Trade-offs: Higher wear resistance steels generally support longer service life, while toughness needs can vary depending on punch load, clearance, and material being punched.

For best results, pair the chosen steel grade with the coded point length to control contact stress and reduce premature wear.

To select the correct ball lock punch dimensions, start by matching the shank diameter (D in) to your die-set punch holder and retainer. This series covers D = 37 ~ 125 in, so confirm the holder bore or machining spec before ordering.

Next, choose the tip shape and the point length coding. The coded point length L is available in ranges such as 250 ～ 600, 250 ～ 700, 275 ～ 700, and 300 ～ 700 (multiple configurations appear in the spec set). The same coded ranges are also listed for B and C point length, and the combined listings include a D point length range of 275 ～ 700 and 300 ～ 700.

• P dimension: 0.05 ~ 1 in
• W dimension: 0.05 ~ 0.5 in
• R dimension: 0.007 ~ 0.007

Because the spec data shows coded inch ranges (rather than fixed lengths), align your choice to the cavity/core stack-up and verify required tolerances in the die-set assembly drawing.
