Inch Standard Regular Punches XNT DayTiN® Coating

These inch-standard regular punches are used as replaceable cutting members in die sets for forming, blanking, and punching, where tool wear directly affects part edge quality and cycle-to-cycle stability. The XNT DayTiN® coating is selected to improve wear resistance at the punch tip during repetitive material shearing and forming operations, helping maintain consistent cutting performance.

• Automotive and appliance bracket/clip dies: Suitable for high-frequency stamping steps where the punch shank must stay dimensionally stable while the cutting edge experiences abrasive wear.
• Electronics housing and connector-related forming: Works well in fine-punching and forming stages that require predictable punch behavior to reduce variation across production runs.
• General metalforming progressive tooling: The coating supports longer tool life in frequent blanking and punching sequences, reducing downtime for punch changes.

Choose a tip shape from H/J/K/L/N/O/R/V/X/Y/Z to match the required cut profile and edge geometry for the cavity/core layout.

The provided data identifies the key performance feature for this punch line as the XNT DayTiN® coated surface. While the specific base steel grade and heat treatment (e.g., nitriding, quench & temper) are not listed in the input, the engineering intent is clear: the coating is used to raise surface wear resistance at the cutting interface and improve tool-life in forming and punch processes.

• Wear resistance: XNT DayTiN® is intended to protect the cutting edge from abrasion and micro-wear during repeated punching.
• Hardness & toughness trade-off: In coated cutting tools, coating hardness improves wear resistance, while toughness is governed largely by the underlying substrate and its heat treatment; selecting the correct tip geometry helps balance edge strength and contact stress.
• Manufacturing process (functional): Punches are produced for repeatable fit within inch-standard tooling so the coated tip can maintain consistent alignment.

For confirmed substrate hardness (HRC) and exact steel grade/heat treatment, request the material certificate for series 250300511233.

Use the specified inch shank diameter D and the coded point length ranges to match the punch to your die set cavity/core requirements. This punch line supports D (shank dia.) from 12 ~ 250 in (as provided) and tip point length coding via standard/alternate length series.

• Tip shape selection: Choose from H, J, K, L, N, O, R, V, X, Y, Z based on the required cut profile at the die opening.
• Point length (B & L coded inch): Standard S is 150 ~ 250. Alternate B options include 150~400, 150~500, 150~600, or 175~600. Alternate C includes 175~600 and 200~700; Alternate D includes 200~600, 200~700, 225~700; Alternate E includes 225~700 and 250~700.
• Profile dimensions: P ranges 0.042 ~ 1.625, W ranges 0.062 ~ 0.5, and R is provided as 0.007 ~ 0.007.

Match the punch length so it fully engages the die cutting zone without bottoming in the guide/holder. If your assembly uses inch standard fits, verify fit class and alignment with your punch holder before locking the final assembly; coated punches should be handled to avoid edge damage that can affect effective working size.
