Straight Regular Punches - Inch

Straight regular punches in inch sizing are used in progressive and single-station punch tooling where consistent part-to-part alignment is critical. The straight punch geometry helps maintain stable positioning against the die opening, supporting accurate forming and clean cut initiation across repeated cycles.

For production of automotive-style connectors and stamped components, the protective surface provided by the DayTride® coating supports longer wear life in high-frequency punching, reducing the rate of edge degradation that can lead to dimensional drift.

In appliance and general metal-forming housings, these punches are well-suited for shops standardizing on inch punch configurations. The inch-series compatibility helps integrate with existing tooling stacks and keeps setups predictable when loading and maintaining DAYTON LAMINA-based punch formats.

• Use when your application demands repeatable die-to-punch alignment.
• Use DayTride® when wear resistance for demanding production cycles is a priority.
• Use inch-series punches to match standardized shop punch configurations.

The provided data specifies this punch series is manufactured with a DayTride® coating, intended to improve wear resistance for punching operations. While the underlying substrate steel grade and heat-treatment state (e.g., quenched & tempered, nitrided) are not included in the supplied specifications, the performance intent is a surface engineered to better withstand repeated cutting and frictional loading.

Key material-related considerations for mold and die engineers:

• Coated surface: DayTride® is applied to support stable tool life under production cycles.
• Wear vs. toughness trade-off: coatings typically improve surface endurance while the base steel primarily governs overall toughness and bending resistance; confirm base hardness and core toughness for your load profile.
• Material comparisons: if you select between uncoated and coated options, the main differentiator here is the added surface wear protection from DayTride®.

For exact base steel grade, hardness (HRC), and heat-treatment condition, request the detailed material datasheet for series 250301145686.

To select the correct straight regular punch dimensions, match your die opening and tooling stack requirements to the fixed ranges in this series. This product series provides a fixed Length (L) range of 150–625 in and a fixed P dimension range of 0.125–0.375 in.

• Step 1: Verify L (Length) against your required penetration/working length and how the punch seats in your holder or punch tool stack. Choose an L value within 150–625 in that supports proper engagement without bottoming.
• Step 2: Confirm P dimension within 0.125–0.375 in. Use this to align with the tooling interface geometry and ensure consistent punching posture.
• Step 3: Fit and tolerance checks—use your punch holder/core standard tolerances to confirm clearance/retention. Because only L and P ranges are provided, consult the relevant DAYTON/LAMINA tooling standard for fit details.

If you are integrating into an existing DAYTON or Lamina configuration, select the inch-series punch that preserves your established stack height and interface dimensions (L and P) for stable alignment.
