The paper reveals and studies the mechanism of the carbide cutting tool wear associated with the vortex deformation modes in the chip near-cutting layers. High deformation degree in the chip near-contact layers causes amorphization of local volumes and rotation of the particles of the material being machined. It is shown that, the torque is additionally acting on the carbide phase grain in contrast to the laminar motion of chip particles in the vortex motion. This circumstance both increases the grains swing amplitude and facilitates their extraction. The ways to increase wear resistance of the carbide tools by deposition of the hard coatings are indicated. Mechanism is described for improving the tool life with the coating deposition on it.
