ることを特徴とする切削工具。[Claims for Utility Model Registration] A cutting tool that finishes a side edge by attaching a chip constituting a cutting portion to the cutting edge and cutting in the width direction of a groove formed on the outer periphery of a workpiece with this chip, The angle formed by the front flank and rake face of the chip is set to a negative angle that slopes upward from the cutting edge facing the workpiece to the base of the cutting tool and forms an obtuse angle with the front flank,
This chip is positioned at the bottom of the groove formed in the workpiece, and from this position, the chip is fed toward the side edge of the groove, and from the bottom of the groove, it is fed toward the opening of the groove. A cutting tool characterized in that the side edge of the groove is finished by using a cutting tool.
