Ball Lock Regular Ejector Punches - Light Duty

Ball-lock ejector punches with a regular light-duty design are used in inch-format injection tooling where ejection reliability is critical but the cycle energy is moderate. The ball-lock geometry improves retention against shifting during repetitive press cycles, helping maintain alignment with the ejector plate.

• Progressive dies for electronics/connector components: Use the light-duty punches to support consistent punching/ejection geometry. The controlled tip profiles help keep part features repeatable.
• Automotive interior or trim brackets (medium-volume): Suitable when the mold requires stable ejector retention but does not demand heavy-duty wear levels. The XNT DayTiN® coating improves resistance to wear and galling at the contact surfaces.
• General housings and fixtures in inch tooling: Ideal for standardized ejector layouts that rely on dependable punch retention. Select appropriate tip shapes to match the required ejection contact area.

This variant is especially suited when long-term sliding contact and repeated ejection can otherwise lead to wear-related performance drift.

This line is available in M2 and PS4 steel options. M2 is a high-speed steel grade commonly selected for its balanced wear resistance and toughness, making it a strong choice for punches exposed to sliding contact and repetitive ejection.

• Coating (applies to the punch surfaces): XNT DayTiN® is specified to enhance surface durability by improving resistance to wear and galling.
• PS4 option: Typically chosen when a different cost/performance balance is desired for light-duty applications.

Because this product listing specifies steel grade options and the XNT DayTiN® coating, material selection should be matched to expected wear severity. For environments with frequent metal-to-metal contact, prioritize the higher wear-resistance selection (often M2) combined with the DayTiN surface treatment. Specific hardness (HRC) and exact heat-treatment state (e.g., quenched & tempered) are not provided in the available data.

Select ejector punches by matching the shank diameter (D), point length, and tip profile to your mold’s cavity/core and ejector plate geometry.

• Shank diameter D (in): choose within 25 ~ 100 to fit the corresponding guide/bushing and punch bore sizing in your inch tooling.
• Point length & overall length L (coded inch): available ranges include 200 ~ 500, 200 ~ 600, 200 ~ 700, and 225 ~ 700 (depending on the code). There is also a fixed-length option listed as 250 ~ 700.
• Point length variants B and C: ranges include 225 ~ 500, 225 ~ 600, and 225 ~ 700 for B/L, while C lists 225 ~ 600 and 225 ~ 700; confirm which geometry your ejector pocket requires.

When substituting, confirm that the effective tip reach (point length) clears the cavity/core surfaces without excessive protrusion. If your design uses slip fits or guided travel, ensure the chosen D aligns with your standard bore tolerance and guide system.
