M2 Steel Ball Lock Pilot Punches - Round Tip, Light Duty, In

These M2 steel ball lock pilot punches are used to establish repeatable part positioning in light-duty inch die tooling, where consistent alignment matters but cutting loads are moderate. The round tip and ball-lock locating action help reduce drift across repeated press cycles.

• Progressive stamping dies: Use the pilot to control feed-to-station registration. The round tip geometry supports predictable entry and the CRN coating helps maintain wear resistance as pilots ride at each station.
• Die alignment fixtures and setup gauges: Fit the shank diameter to the fixture bushings/locating holes to improve indexing repeatability during tool changeovers.
• Automotive and appliance connector/terminal forming: In part profiles that require stable hole/feature registration, the ball lock helps maintain secure alignment without requiring heavy-duty pilot components.

Choose the M2 + CRN variant when you need a balance of locating stability and practical wear life for light-duty stamping applications.

This product is offered in M2 (and also PS4 per the available material options), designed for pilot applications that benefit from good wear resistance and toughness. M2 corresponds to AISI M2 high-speed steel, commonly selected for cutting-edge and wear-intensive locating components.

• M2 behavior: Typically used in a hardened condition (commonly quenched and tempered for HSS performance). Expect strong abrasion and micro-wear resistance from its high hard carbide content, with toughness governed by the tempering level.
• CRN coating benefit: The durable CRN coating supports stable surface wear resistance during repeated press cycles, reducing rounding/fit loss at the round tip.
• Trade-off vs PS4: PS4 is available as an alternative material option; for final selection, compare your desired wear life versus toughness and expected loading per your press environment.

Exact hardness in HRC is not specified in the provided data; hardness should be confirmed on the coating/material certification for your build.

To select the correct ball lock pilot punch dimensions, start with the mold/die interface requirements for the shank diameter (D) and pilot travel/point geometry. The shank diameter range is 25 ~ 100 in, so match this value to the locating hole/bushing ID used in your die.

• Point length selection: Choose the correct coded point length L from 200 ~ 500, 200 ~ 600, 200 ~ 700, or 225 ~ 700, according to the available stack height and engagement depth.
• B/C options: The data includes B & L ranges of 225 ~ 500, 225 ~ 600, 225 ~ 700, and C ranges of 225 ~ 600 or 225 ~ 700; ensure your assembly has clearance for the chosen profile.
• P dimension (in) sizing: Set the P dimension within 0.05 ~ 0.749 to achieve the intended ball-lock engagement and locating offset.

Confirm fit/tolerance behavior with your corresponding bushings/holes: pilot systems typically require controlled clearance to prevent binding while maintaining repeatability.
