Center Dowel Punches for Heavy Load - Metric

Center dowel punches like this heavy-load metric variant are used in the die set to establish reliable center alignment during repeat production cycles. They are particularly effective where registration accuracy directly impacts downstream forming or casting features and where misalignment can cause tool wear or part defects.

• Automotive die casting & stamping: Use the punch in the bolster/die receiver interface to improve part-to-die registration repeatability, especially when the forming load is high and the tooling experiences frequent cycles.
• Heavy-load progressive forming: Pair with matching cavities/locating features to maintain positional stability across multiple stations; the available tip geometries support mating with different alignment recesses or pilot profiles.
• Industrial appliance housings: For housings requiring consistent concentricity and feature alignment, select the point length and profile-related parameters to stabilize locating under demanding die conditions.

The metric, ejector-style configuration with multiple shank diameters (10–25 mm) and point lengths (13–19 mm, 19–25 mm) makes it suited for heavy-duty die systems where stable center location is required.

The provided metadata does not specify the exact steel grade, hardness (HRC), or heat treatment state for this DAYTON center dowel punch series. Because key wear and toughness performance is strongly tied to the steel and heat treatment, those details should be confirmed from the product datasheet or material certificate for final engineering qualification.

What you can control from the configuration data:

• Tip and profile-related dimensions (tip shape, P, W, and R ranges) to tune contact mechanics and locating repeatability.
• Point length (L1) selection (13–19 mm or 19–25 mm) to manage lever effects under load.
• Shaft diameter (D) selection (10, 13, 16, 20, 25 mm) to balance rigidity versus packaging constraints.

In general, harder tool steels improve wear resistance, while tougher states (tempered structures) can reduce chipping risk at high contact stress; verify the actual spec for the selected configuration.

Select the punch dimensions by matching the shank diameter, overall length, and point geometry to the corresponding locating feature in your die set. This series supports D = 10, 13, 16, 20, or 25 mm with a fixed L = 80–130 mm, plus selectable point length (L1) ranges of 13–19 mm or 19–25 mm.

• Match D: Choose the shank diameter that fits the die block/bushing bore. Confirm any press-fit or sliding-fit requirements with your receiving-hole tolerance stack.
• Set L (fixed): Ensure the 80–130 mm length provides correct engagement depth and clearance for ejector/locating movement in your tooling layout.
• Match tip geometry: Select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and align contact parameters P (4–18 mm), W (4–6 mm), and R (0.2–5, 0.2–6.5, 0.2–8, 0.2–10, 0.2–12.5 mm) to the mating feature.

If your design uses close tolerance locating, request the configured tolerance/fit data for the selected tip shape and R range; the metadata provides dimension ranges, not tolerance class.
