Wilson produces two case mouth deburring tools for use in the Wilson Case Trimmer. The deburring tools mount in the cutter bearing and each includes a crank style handle. Cases are held in the trimmer case holders and are held square to the deburring tool. This tool deburs the inside of the case mouth only. The tool is available in the standard 45-degree (WUD45) chamfer and in a 30-degree (WUD30) chamfer for use with VLD bullets. The handle is included, but can be removed to use a Sinclair power adaptor (WSA) so you can power the operation with a drill or rechargeable screwdriver. Not recommended for use on brand new cases.
