However, when such a means is adopted, a notch for inserting the wedge member is formed, so that a free end portion is formed at the notched portion. At the same time, the rigidity of the tool body around the notch decreases. Therefore, if the wedge member is inserted in the inner peripheral direction in this state, distortion occurs in the weakened part of the tool body, which appears as a deflection of the tool body, resulting in the dimension of the workpiece. It was unavoidable that the accuracy deteriorated.

Further, when a plurality of chips are provided on the outer circumference of the tool body, the tool body must be scraped off as described above, so that the rigidity of the tool body is unavoidably reduced, which causes chattering and the like during cutting. However, as a result, the accuracy of the finished surface may decrease. And this tendency becomes particularly remarkable in the throw-away type rolling tool in which the wall thickness of the tool body is limited such as a metal saw.
