This cutting tool makes drilling and deburring by one machining operation. That is, as soon as drilling of through hole has been finished, the exit burr generated will be removed by the tool itself that has two additional deburring cutting edges. Addition of the edges to spade and twist drills was done. It was made to the cutting part in the case of a spade drill and to the newly produced part by reducing some part of the body in the case of a twist drill. The former is used large hole and the latter is for small hole. For the processing of deburring, countouring control (circular interpolation) in a CNC machining centre was employed. Edge quality of hole after deburring was fine and the effectiveness of this method of deburring for practical use was investigated.
