M2 Steel Ball Lock Regular Ejector Punches Light Duty Metric

Ball-lock regular ejector punches with M2 steel are used in light duty metric stamping tooling where reliable blank release is required during repeated press cycles. The ball-lock point provides repeatable positioning, helping reduce misalignment-related wear and preventing partial sticking of blanks.

Automotive stamping is a common scenario: these punches support consistent ejection from punch-and-die sets, especially for thin or moderate-friction materials where clean release improves downstream forming quality.

Appliance and enclosure component stamping benefits as well, because stable ejection timing helps maintain part edge integrity and reduces the risk of secondary marks caused by dragging.

• Choose this variant when you need stable, cycle-to-cycle ball-lock action for clean part ejection.
• Match the tip shape options (H–Z) and the M2 material to your part geometry and material stack-up for predictable performance.

This series is offered in M2 steel (and also PS4 as an alternative). M2 is a high-speed steel grade commonly selected for tooling that balances wear resistance with adequate toughness for light forming and stamping cycles.

In heat-treated condition, M2 is typically quenched and tempered to achieve a hardened microstructure that improves resistance to abrasion from sliding and contact at the punch point. The main trade-off is that increasing hardness for wear control can reduce toughness, so the selected heat treat should align with your stamping load profile.

• M2: high hardness after quench & temper supports longer life under repetitive contact.
• PS4 (if selected): provides an alternative material option; choose it when your application preference is material-specific to your supply/process constraints.

Hardness (HRC): not specified in the provided data, so confirm your receiving/heat-treat certificate to validate the exact hardness target for your production requirements.

To select the correct ball-lock regular ejector punch, match the shank diameter (D) and the overall length (L) to your die set layout and guide requirements. Available D range is 6 to 38 mm.

Then choose the point length L1 from the provided ranges (10–13, 10–19, 13–25, or 19–30 mm), ensuring the ball-lock point reaches the blank far enough to eject cleanly without bottoming in the die.

Overall L options include 63–100, 71–100, and 80–100 mm, depending on the punch length you need for your ejector system travel and stop geometry.

• Confirm the P dimension (1.4–12 mm) and W dimension (1.4–14 mm) against the mating recess/lock features in your ball-lock receiving design.
• The provided R dimension is 0.2 mm; use it to ensure the point profile matches your ejection and part clearance requirements.

Tolerance/fit: not specified in the provided data—use your die builder’s standard tolerance stack and validate fit with the corresponding ball-lock pocket geometry in your tooling.
