Abstract
An object is to provide a vibration suppressing cutting tool which is inexpensive and can damp chattering extremely effectively, and which is simple in structure and is applicable to a wide variety of machining diameters and cutting conditions. The shankof the holderis formed with a pocket. In the pocket, a vibration suppressing pieceis received so as to be movable relative to the holderand not protrudable from the pocket. Under kinetic energy from the holder during cutting, the vibration suppressing piecealternately knocks against a pair of opposed inner wall surfacesandof the pocket along its surface, along a plurality of lines or on a plurality of points when the holder vibrates during cutting, thereby damping vibrations of the holder.
