Inch Regular Punches (XN DayTride Coating) by DAYTON

This inch regular punch series is used in press tooling where stable material forming and consistent hole/feature generation are required. The XN DayTride® coated working surface helps reduce cutting wear, supporting steadier performance across production runs with standard punch-and-die engagement.

• Automotive and appliance stamping: Ideal for repeatable forming features in close-tolerance progressions. Select the required tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to match the die opening geometry while benefiting from reduced wear at the cutting interface.
• General metal forming and fabrication: Suited for tooling sets built on common punch layouts. Use the broad shank diameter range (12–250 in) and coded point-length options to align with established station spacing and stack-up.
• Job-shop low-to-medium volume production: When tool change frequency matters, the coating’s wear reduction supports longer life under typical press conditions while keeping punch selection straightforward.

The provided data specifies an XN DayTride® coating on inch regular punches, engineered to reduce cutting wear during stamping operations. While the underlying steel grade and exact heat treatment state (e.g., quenched & tempered, nitrided) are not included in the supplied specifications, the coating’s function is to improve wear resistance at the punch working surface where friction and cutting stresses concentrate.

• Wear resistance vs. toughness trade-off: Coated variants typically prioritize surface durability for consistent edge performance; the base metal selection and heat treatment largely govern toughness and resistance to chipping.
• Manufacturing process relevance: Coating application is intended to maintain a stable cutting interface during production, helping preserve dimensional consistency over successive strokes.

For material-specific hardness (HRC) and heat treatment confirmation, request the full technical sheet for the selected tip shape and size.

Select punch dimensions by matching the shank diameter, point length (coded), and the tip shape to your die opening, strip layout, and press station space.

• Shank diameter (D): Choose from the provided range of 12–250 in to ensure proper fit in the guide system and stable alignment during punch-and-die engagement.
• Point length/overall length (B & L coded inch): Use the standard 150–250 code range or alternate options such as 150–400, 150–500, 150–600, 175–600, 200–700, 225–700, or 250–700 based on your tool stack-up and required penetration.
• Head/edge geometry (P, W, R): Confirm P: 0.042–1.625 in, W: 0.062–0.5 in, and R: 0.007–0.007 in for the cutting interface profile that corresponds to the die land and clearance strategy.

Because the data uses coded inch lengths, verify the code-to-length mapping from the manufacturer drawing. Maintain alignment and allowance in the punch holder to account for coating thickness and normal tooling tolerances.
