Straight Regular Punches Metric XCN Coating

These straight punches with XCN coating are used in injection mold tooling when stable, repeatable shearing or punching actions are needed in insert frames, tryout tooling, and production die sets. Their straight regular geometry helps maintain alignment through the press stroke, which supports consistent cutting engagement and reduces the risk of edge chipping during high-cycle runs.

• Fabrication and stamping/blanking dies: Ideal for punching sheet or strip features where a straight punch must deliver uniform penetration across repeated cycles.
• Multi-cavity die inserts: The available P dimension (3–16 mm) supports common die set layouts and helps engineers map punch location and clearance strategy to each cavity.
• Production tooling requiring longer service life: The XCN-coated surface improves wear resistance at the working interface, supporting more consistent cutting performance.

Select this variant when you need dimensional fit to the cavity/core layout (available L = 50–100 mm) and when coating-enhanced durability helps stabilize tool life under steady production loads.

The provided data specifies this product as a straight regular metric punch with XCN coating, but it does not list a steel grade or post-heat-treatment condition. As a result, exact baseline hardness (HRC) and specific alloy equivalency (e.g., SKD61/H13) cannot be confirmed from the supplied specifications.

From an engineering standpoint, the key material-related differentiator here is the XCN coating, which is typically chosen to improve surface durability and wear resistance at the punch/work contact. That usually leads to a favorable tool-life/edge-stability trade-off under repeated punching, especially when abrasive wear and micro-surface damage become dominant.

• Coating effect: Enhances resistance to wear and helps maintain cutting performance over repeat cycles.
• Trade-off: Coatings can be more sensitive to edge damage from misalignment; therefore, geometry stability and correct fit are critical.

For precise hardness and heat-treatment targets, request the steel and coating spec sheet for series 250301354239.

To select the correct punch size, match the punch length L (50–100 mm) and P dimension (3–16 mm) to your die set stack-up and punch guidance geometry. In practice, L must provide sufficient working engagement while allowing clearance for holder length, stop surfaces, and safe stroke depth.

• Match L to die height: Use the required protrusion and the press stroke rules to ensure the punch reaches the intended cutting depth without bottoming out.
• Set P dimension to layout: Choose the P value (3–16 mm) that fits the cavity/core and die block arrangement, supporting consistent punch positioning in the tooling.
• Consider fit and tolerance: Confirm functional clearances between punch and die opening in your drawings; misfit or misalignment can accelerate edge wear, especially for coated punches.

All listed dimensions here are fixed ranges by the series: you select specific values within L = 50–100 mm and P = 3–16 mm. If your layout requires a non-standard step, verify compatibility with your die insert design before finalizing.
