M2 Steel Ball Lock Regular Ejector Punches - X Tip

These M2 steel ball-lock regular ejector punches are used in injection mold tooling where ejector reliability directly impacts cycle stability. The X-shaped tip helps the ball-lock mechanism seat consistently during opening strokes, reducing the risk of partial engagement under high repetition.

• Automotive & industrial components: In metric die sets, the robust engagement supports repeatable ejection for thicker parts and demanding press cycles, helping maintain consistent part release.
• Appliance and housings: For ejector systems that must withstand frequent thermal cycling, the wear-focused punch construction supports stable lock performance while ejecting larger surface-area components.
• Heavy-duty precision tooling: When a ball-lock design is required for quick, modular maintenance, the X-tip geometry is suited for maintaining proper seating and dependable ejection timing.

Choose this variant when the ball-lock seating behavior and ejector repeatability are critical in a metric tooling environment.

This series is available in M2 steel or PS4. M2 (a high-speed steel commonly used in tooling) is selected for its strong wear resistance, supporting longer ejector punch service life under frequent sliding/impact conditions. PS4 is offered as an alternative material option for designs where a different balance of machinability and performance is desired.

• Heat treatment: Ejector punches in steel tooling applications are typically provided in a heat-treated state suitable for punch operation; the exact hardness level depends on the supplied variant.
• Hardness & performance trade-off: Higher hardness generally improves wear resistance but can reduce toughness, so material selection should align with expected loads and ejection forces.
• Manufacturing: The punches are produced to controlled shank and tip geometry (including the X-shaped tip) to maintain ball-lock seating stability.

For maximum wear durability in heavy-duty metric tooling, M2 steel is the primary selection within this series.

Select the correct ejector punch dimensions by matching the shank diameter (D), overall length (L), and point length (L1) to the cavity/core ejector design and assembly stack-up.

• D (Shank dia.): choose from 10 ~ 40 mm to match the guide bore and ejector retention features in your tooling.
• L (Length): select from 63 ~ 125 mm, with additional available bands of 71 ~ 125 mm and 80 ~ 125 mm depending on the specific configuration.
• L1 (Point Length): available in 10 ~ 19 mm, 13 ~ 25 mm, or 19 ~ 30 mm—use this to achieve the required ball-lock seating depth and effective ejection stroke.

Confirm the P and W feature dimensions (each 1.5 ~ 12 mm for P and 1.5 ~ 14 mm for W) against the mating ball-lock components. Where fit is critical, verify tolerances in the punch’s shank-to-guide interface and ensure the tip geometry is compatible with the ball-lock housing to prevent mis-seating.
