Udico Mandrel and Plug Products


The United Die Company produces tungsten carbide mandrels and plugs in a variety of sizes and configurations. Mandrel products (sleeve-type, braze-type, and shape-type) can be supplied with wrench flats, nib-only configurations, and in non-standard sizes. Plug products are available with or without brazed stems and to customer specifications.
