Point Larger than Shank Regular Ball Lock Punches Light Duty, Inch

This light-duty ball-lock punch is used in injection-molding tooling where consistent ejection and secure punch retention are required. The point larger than shank geometry improves engagement stability, helping maintain predictable lock-up during repeated cycling.

• Automotive and appliance part ejection: suited for standard die sets and ejector systems that demand reliable ball-lock retention without heavy-duty wear expectations.
• Progressive tooling for small plastic components: the stable point-to-shank form supports alignment, which helps reduce wobble and maintains consistent part release geometry.
• General-purpose mold builds in inch tool design: available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow matching contact profiles to part surfaces for controlled ejection.

The XNT DayTiN® coating is intended to reduce abrasion and extend usable life in production cycles where ejector elements experience friction against inserts and molded parts.

The provided data specifies an XNT DayTiN® coating on a light-duty ball-lock punch, with no steel grade or hardness values listed. DayTiN® type coatings are typically selected to improve wear and abrasion resistance while maintaining practical toughness for repeated ejection cycles.

Because the underlying steel specification (grade), heat-treatment state (e.g., quenched & tempered, pre-hardened, nitrided), and target HRC hardness are not included in the input, those values cannot be stated accurately for this product variant.

• Coating benefit: improved resistance to rubbing wear during part ejection.
• Trade-off: coating thickness and chemistry can slightly affect dimensional response; verification is recommended when tight functional fits are required.
• Material comparison: no alternative steel grades or coating variants were provided in the specification data, so only the coating effect can be addressed.

To select the correct punch size, match both the shank diameter (D) and the point-to-shank engagement geometry to your core/cavity ejector layout and the ball-lock pocket dimensions.

• Shank diameter (D): choose from 37 (0.3750), 50 (0.5000), 62 (0.6250), 75 (0.7500), 87 (0.8750), or 100 (1.0000) in.
• Length (L, coded inch): confirm the required stroke/stack height using L in the range 250–450.
• P dimension: use the matching range for your style: 0.376–0.875, 0.501–1.25, 0.626–1.5, 0.751–1.5, 0.876–1.75, or 1.001–1.75 in.
• W and R: set the profile with W = 0.062–0.867 in and R = 0.007–0.4375 / 0.007–0.625 / 0.007–0.75 / 0.007–0.875 in depending on the selected configuration.

Plan for functional fit by verifying the selected D and point geometry against your ejector plate hole and ball-lock receiver dimensions; tolerance requirements are not provided, so confirm with your mold drawing standards and supplier datasheet.
