Straight Regular Punches Inch (XNAD Coating)

These straight regular punches are used in production-grade injection and forming tooling where high repeatability punching is required, especially for operations such as blanking, piercing, and forming pre-features that later support molded assembly components.

• Automotive connector and bracket tooling: The straight geometry supports consistent alignment within standard inch press setups, helping maintain stable hole location as cycle counts increase. The XNAD coating helps control edge wear for longer punch life.
• Appliance and electronics sheet fabrication: Use when maintaining cutting edge integrity is critical to reduce dimensional drift across runs. The controlled P-dimension configuration supports predictable strip handling and press repeatability.
• General fabrication runs: Suited for applications where reliable punch life and stable output are valued over highly specialized micro-punch requirements.

With lengths in the 150–625 in range and a P dimension of 0.125–0.375 in, this variant can be matched to common press configurations to support consistent, accurate punching performance.

The provided specification focuses on dimensional ranges and the XNAD coating performance layer, rather than a specific steel grade or heat-treatment state. As such, material-selection claims (e.g., exact hardness HRC, quenched-and-tempered condition, or nitriding) cannot be stated from the available data.

For coated punch applications, the engineering intent is typically to improve wear resistance at the cutting edge and help preserve dimensional accuracy during high-cycle production. The XNAD coating supports longer tool life by reducing abrasive and adhesive wear mechanisms.

• Coating-first durability: Expect the main durability benefits to come from the XNAD surface system.
• Toughness trade-off: Coatings generally improve surface performance while core toughness still governs resistance to chipping under misalignment or shock loads.

If you need confirmed steel grade, target hardness (HRC), or a specific heat-treatment route for your build standard, share your drawing requirements and we can align the specification accordingly.

Select the correct punch size by matching both L (Length) and the P dimension to your press tooling stack-up and the intended piercing depth/engagement profile.

• Length (L): Choose a fixed L within 150–625 in based on your press opening, holder/projection requirements, and the required penetration depth for the formed feature.
• P dimension: Select P in the range 0.125–0.375 in to match the configured press interface and the geometry relationship your tooling uses for alignment and engagement.

To minimize positional variation, ensure the selected dimensions are consistent with the core/cavity interaction equivalent in your die set—where the punch’s alignment and engagement determine hole location and size stability. If your drawing specifies tight tolerances on pocket depth, holder seating, or press stop heights, treat the punch dimensions as the primary “driving” dimensions and confirm the mounting hardware tolerances so the effective working length matches what the die set expects.

This product variant uses fixed ranges for L and P (no variable dimensioning within the spec), so confirm your cavity/punch engagement requirements before final selection.
