A rotary cutting tool fed along its axis of rotation is used for cutting processes in which teeth of the tool do not continuously engage a workpiece, such as forming a cope. A cylindrical body of the tool is fluteless in order to keep the tool's cutting swath to a minimum thickness and thus reduce the cutting forc es and heat generation from those of conventional annular metal cutters. Circumferential spacing of teeth about an annular end face of the body acts to contain material removed from the workpiece until reaching a portion of the tool's rotational path in which the workpiece is not engaged, at which point the material is freed fro m the tool to prevent jamming. An outer surface of the cylindrical body is continuous over a substantial majority of its length in order to ensure adequate tool strength . |
