M2 Steel Ball Lock Regular Punches Heavy Duty X-Shaped Tip

These heavy-duty ball lock regular punches with an X-shaped tip are designed for repeatable blank separation in production die sets. The ball lock retention helps hold the punch position under dynamic press loads, reducing drift that can lead to edge defects or inconsistent ejection.

• Automotive and general stamping: Use in progressive or compound dies for metal blanking and forming where stable punch alignment is critical to maintain consistent shearing and stripping.
• Electrical connector and terminal dies: The X-shaped tip geometry supports dependable stripping, helping protect fine features during ejection of closely toleranced blanks.
• High-cycle forming tooling: The heavy-duty construction suits long-running operations where wear resistance and point stability reduce maintenance frequency.

With the selectable M2 steel option, this variant is well matched to applications that demand good wear performance while maintaining reliable point contact during repeated press cycles.

M2 steel punches are selected for their high hardness and strong wear resistance typical of tool steels used in blanking and forming. For this series, hardness and exact heat-treatment values are not provided, so engineers should confirm the supplied hardness/treatment state with the material certificate for your order.

In practice, M2 punches are commonly quenched and tempered to achieve a hard, wear-ready balance; the trade-off is that higher hardness improves abrasion resistance but can reduce toughness if impact loads are severe. The alternate PS4 material is offered as a configuration choice for different wear/production requirements, allowing you to tailor performance to your cycle conditions.

• X-shaped tip geometry complements the steel choice by supporting stable stripping contact.
• Wear vs. toughness: Expect wear resistance to improve with harder heat treatment, while toughness becomes more sensitive to loading and alignment.

To select the correct ball lock regular punch, match the shank diameter D and length to your guide and cavity/core requirements. This series covers D values of 10, 13, 16, 20, 25, 32 mm, enabling compatibility with different die block sizes and guide arrangements.

• Point length (L1): choose from 10–19 mm or 13–25 mm based on how deep the point must reach for proper stripping/blank separation.
• Total length (L): select from 63–125 mm or 71–125 mm to ensure sufficient protrusion while maintaining guidance length.
• P and W dimensions: use P = 1.5–10 mm and W = 1.5–12.5 mm to align the tip profile and contact width to the stripping and shearing interface.
• R dimension: select the required radius range (from 0.2 up to 4.98 / 6.48 / 7.98 / 9.98 / 12.48 / 15.98 mm) to suit your land/contact geometry.

These dimensions are provided as variable configuration ranges; keep in mind that final fit also depends on your punch bore and retention fit for the ball lock system.
