Abstract
The cutting tool insertis in a substantially plate form and of polygonal shape and is provided with a major cutting edgeA (orB) extending from one cornerA (orB) toward the other cornerA (orB). The major cutting edgeA (orB) comprises a first edge line and a second edge line that meet to form an obtuse angle, which causes the area where the first and second edge lines meet to protrude slightly outwards, as viewed from above. The first edge line slopes down towards the second edge line so that the distance with a seat facedecreases gradually as viewed from the side, and the first edge line forms an obtuse angle with the second edge line causing the top face area to dip down towards the seat face. The first edge line is shorter than the second edge line.
