Point Larger than Shank Ball Lock Punches - Light Duty, Metric, XAN DayTAN™ Coating

Where it’s used: This point larger than shank ball-lock punch is selected for light-duty mold and die tool applications that rely on stable ball-lock retention and predictable alignment during cycling.

• Progressive dies & stamping tools: Use the larger point geometry to improve guidance and help preserve repeatable tool positioning as parts advance. The XAN DayTAN™ surface support helps resist wear in high-cycle stamping environments.
• Light-duty metric die casting tooling: In die sets where ejector components must maintain controlled dimensions, the coating helps extend ejector life by reducing abrasive and contact wear at the point region.
• Injection mold tooling with ejector/guide punch interfaces: The point larger than shank design supports tight fit by maintaining controlled point dimensions, which can improve ejection consistency where ball-lock retention is critical.

This product is specified as a light-duty ball-lock punch variant with an XAN DayTAN™ coating, selected to improve wear performance during high-cycling tooling. The provided data does not identify a specific base steel grade, heat-treatment recipe, or numeric hardness (HRC), so material state should be confirmed on the project documentation or from the supplier’s material certificate for your exact configuration.

• Coating function: The XAN DayTAN™ coating is engineered to resist wear at the point contact area, supporting longer ejector life and more stable operation over time.
• Wear vs. toughness trade-off: Coatings typically increase surface resistance to abrasion and scuffing, while toughness and core strength remain governed by the underlying steel and its temper condition.
• Comparing variants: If higher duty is required, engineers often move from light-duty coated punches to harder, through-hardened or nitrided options; this configuration prioritizes wear resistance for light-duty metric use.

Selection workflow: Choose the punch based on the point and shank geometry that must fit the mating ball-lock receiver and guide interface in your mold or die set.

• Match shank diameter D: Select from 13, 16, 20, 25, 32 mm to align with the receiver’s shank bore and retention feature.
• Verify point length L1: L1 = 19–30 mm to ensure the point engagement depth provides stable guidance without bottoming.
• Confirm overall length L: L = 80–100 mm so the punch protrusion and tool stack-up meet your ejection or actuation stroke requirements.
• Use P, W, and R to fit critical profiles: P ranges include 13.1–32, 16.1–38, 20.1–40, 25.1–44, and 32.1–50 (with related variants shown in the spec list); W is 1.57–27.8 mm, and R is 0.2–16 / 0.2–19 / 0.2–20 / 0.2–22 / 0.2–25 mm depending on the point shape.

Tolerance & fit: Because the design supports “tight fit” by maintaining controlled point dimensions, use engineering drawings for the mating cavity/core tolerances and confirm that the selected coating thickness and profile tolerances are compatible with your receiver dimensions.
