Tool for chip removing machining includes a shank having a clamping end and a cutting insert at an opposite end, plus a number of piezo-elements for dampening vibrations therein. A pair of cooperating, flat-shaped piezo-elements with lengths that are shorter than that of the shank, are placed on opposing sides of the shaft in an area adjacent to the region where the shank is secured in the machine wherein the direction of polarization of the piezo-elements is parallel to the longitudinal axis of the shank. The piezo-elements constitute actuators that are actively steerable through the application of a voltage from a source of electricity via a control device in the form of a logic control circuit, to thereby dampen the bending vibrations of the shank.
