Straight Regular Punches - Metric, XCDP Coating

Straight regular punches with a metric layout are used as cutting elements in injection-mold-adjacent press tooling, particularly for blanking and punching stations in progressive and transfer dies. Their straight geometry supports stable alignment as the punch penetrates the sheet, which helps maintain dimensional consistency over long production cycles.

In automotive connector and electrical bracket fabrication, the XCDP-coated surface is suited for repeatable blanking runs where abrasive wear and die face contamination can reduce tool life. The coating helps improve wear resistance, supporting consistent stroke-to-stroke performance.

For appliance sheet-metal parts and housings, these punches are commonly selected when the die build uses standardized metric dimensions. The available length range (50–100 mm) and punch diameter range (P = 3–16 mm) allow engineers to match punch reach and cutting clearance within typical progressive tooling stacks.

• Progressive/transfer dies for stable blanking and punching
• XCDP coating supports wear life for repeatable runs
• Metric dimensions align with standardized press die layouts

The provided specifications specify XCDP coating as the key functional surface treatment for wear resistance, but no base steel grade or hardness (HRC) is stated in the available data. Therefore, material properties such as toughness/tempering and exact HRC cannot be confirmed from the supplied parameters.

In typical tooling practice, wear-focused coatings like XCDP are selected to reduce abrasive wear during punching and to help maintain cutting-edge geometry. The main trade-off is that surface coatings prioritize wear resistance and edge stability, while extreme toughness performance depends on the underlying punch steel and its heat treatment.

To select the correct straight regular punch, start by matching the required P dimension (3–16 mm) to the punch diameter required by your blanking/punching feature. This diameter must align with the intended hole size and clearance strategy of the progressive or transfer die.

Next, choose L (Length) = 50–100 mm based on the press tooling stack-up, including die shoe thickness, stripper plate clearance, and the required punch reach to achieve full material penetration without overtravel interference.

• Match P: choose P within 3–16 mm for the target punched feature geometry
• Match L: select L within 50–100 mm to cover the die build stack-up

Tolerance and fit should be handled in the context of your punch holder/bushing system and die layout; while no tolerance values are provided here, ensure compatibility with your standard guided punch supports and alignment requirements for straight punch geometry. If your tooling is metric-standardized, keep all related die components in the same metric dimension framework.
