A cutting tool for internal and external turning has a body with straight main cutting edge, a curved auxiliary cutting edge, and a chip guiding shoulder extending in parallel to the feed advance direction of the tool. The main cutting edge forms a tangent to the curved auxiliary cutting edge. Further, the main cutting edge encloses an angle of 3 DEG to 9 DEG with the direction of the chip guiding shoulder an normally with the feed advance direction. This construction makes the tool substantially independent of tool positioning errors whereby the cutting quality is increased. |
