DAYTON Point Larger than Shank Ball Lock Punches - Heavy Duty, Inch, XN DayTride

These heavy-duty ball lock punches with an enlarged point-to-shank geometry are designed for industrial injection-mold tooling support where consistent blanking, guidance, and part release stability are critical.

• Automotive connector and latch component inserts: Use in progressive die stations to maintain reliable hole formation and predictable ejection, reducing dwell-time sensitivity during high-throughput production.
• Medical device housing and adaptor plates: The stable ball lock engagement helps keep punching position repeatable across cycles, supporting clean hole release and minimizing edge damage in thin-wall workflows.
• Electronics enclosures and precision sheet-metal features: The XN DayTride® coating is suited for repeated stripping by improving wear resistance and reducing frictional buildup on the punch tip.

The enlarged point relative to the shank improves load distribution at the cutting interface, supporting demanding punch-and-die setups where stable release and durable stripping performance are required.

This series is specified around an XN DayTride® coating, selected to enhance surface performance during repeated stripping and punching cycles. The coating’s primary benefits are improved wear resistance and more stable clean hole release by lowering friction at the contact interface.

• Coating effect: Helps resist abrasion and galling tendencies that can accumulate on punch points under high cycle counts.
• Heat treatment: The input data provides the coating specification focus; no base steel grade or explicit hardness (HRC) is provided here.
• Trade-off: As with typical coated punches, coating improves durability, while the base substrate’s toughness-to-wear balance (not specified in the data) governs edge chipping resistance.

If you need exact hardness and temper conditions for qualification, request the material/heat-treatment certificate for the specific point shape variant (H, J, K, L, N, O, R, V, X, Y, Z).

Select the punch based on the shank diameter D = 37 to 125 in, then choose the length L from the available coded inch ranges (250–450 or 275–450 depending on the variant). Confirm the point-related dimensions to match cavity/core geometry and the required cutting profile.

• Tip geometry: Choose the Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z) and then match P (0.376–1.251 in) and W (0.062–1.083 in) to the target hole size and stripping clearance envelope.
• Radius/edge blend: Set R according to the available range for your variant: 0.007–0.4375, 0.007–0.625, 0.007–0.75, 0.007–0.875, or 0.007–1.
• Fit considerations: Ensure the selected D supports the ball lock fit and that the length L provides required engagement without bottoming in the punch housing.

Because only dimension ranges are provided, use your mold builder’s drawings to verify clearance and any required tolerances for the station/tooling interface.
