Cutter inserts are provided with a circumferential primary bevel whose width is between 0.05 to 0.2 mm and which has an angle of inclination downward from the top surface of between 20 and 35 degrees. The primary bevel is adjoined by a secondary bevel which has a width between 0.5 and 2.0 mm and an inclination downward from the top surface between 5 and 15 degrees. The primary bevel is at an angle .alpha. between 5 and 15 degrees with respect to the secondary bevel. At the corner radii the secondary bevel comes to an end and thereby forms the strengthened area.
