Close Space Straight Punches - Inch XCD Coating

Close-space straight piercing punches are used in injection mold tooling when the press fit between die components is tight and alignment must remain stable across repeated strokes. The straight punch profile helps maintain guidance through each cycle, making it suitable for compact blanking operations in small-footprint tools.

• Automotive and appliance trim/connector stampings: ideal for piercing in narrow die sets where limited clearance requires consistent punch alignment.
• Electrical housing and thin metal insert piercing: the inch punch format supports compatibility with North American die and punch assemblies while delivering clean, repeatable blanking.
• High-frequency production tooling: the XCD coating on this variant is selected to improve surface wear resistance and help extend service intervals in abrasive piercing conditions.

Choose the regular head (KCX) for straightforward alignment needs, or the angled head (KWX) when tooling geometry benefits from an angled entry while still operating within close-space constraints.

The provided specifications describe the punch’s XCD coating and head geometry options (KCX regular head or KWX angled head), but do not list the underlying steel grade or heat treatment state. As a result, hardness (HRC), quenched & tempered condition, nitriding, or any specific steel equivalent cannot be confirmed from the supplied data.

• XCD coating role: intended to improve surface resistance to wear for longer service life under piercing/blanking loads.
• Wear vs. toughness trade-off: coatings typically enhance surface durability, while the base steel’s toughness governs resistance to chipping under shock; however, these base properties are not stated in the current dataset.
• Material comparison: no alternate steel grades are provided in the input; comparisons between grades (e.g., H13 vs. PM tool steels) cannot be made reliably here.

For final material selection and hardness verification, request the steel grade and heat treatment documentation tied to series code 250301145507.

Select sizing by matching the punch L (Length) and P Dimension to the die set design requirements for support length and piercing clearance. For this series, L is 150–400 in and P is 0.04–0.25 in, so you should verify that your tool’s available punch stroke and guide/support depth can accommodate the chosen L.

• Match L to stack-up: choose the smallest L that fully spans the required guide/support and still provides stable alignment through the stroke.
• Match P to clearance/control requirements: set P within 0.04–0.25 in based on the die opening, punch-to-die clearance strategy, and the close-space envelope of the tool.
• Head selection: use KCX (regular head) when your die set favors straight engagement, or KWX (angled head) if the tooling layout requires an angled entry while remaining in the close-space clearance region.

Tolerance and fit limits are not provided in the dataset; confirm required fits against your die block tolerances and punch holder guidance specs before machining or final assembly.
