  • the clearance angles of the flank sections are selected so that the clearance angle is greatest at the cutting edge and gradually decreases in the direction of the cutting insert contact surface.

  • the free area is divided into three, the upper area forming a clearance angle between 7 ° and 20 °, the lower area a clearance angle between 0 ° and 15 ° forms and the intermediate area forms a clearance angle of 0 °.
