  • Cutting tool for internal and external turning operations
    Patent number: 4371296

The main cutting edge forms a tangent to the curved auxiliary cutting edge. Further, the main cutting edge encloses an angle of 3.degree. to 9.degree. 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.
