ABSTRACT:
Cutting insert and tool, wherein the tool has a seat formed by at least 190 degrees of a cylindrical seat surface, and the insert has an outwardly projecting region forming a cutting edge and three convex regions simultaneously touching the cylindrical seat surface at three distinct points. Those points form an imaginary triangle with all angles acute. A center of the cylindrical seat surface lies within the imaginary triangle, and a center of gravity of the insert lies outside of the imaginary triangle. The insert can only be removed from the seat after being rotated by a prescribed angle away from its cutting position.
