Abstract
Intersecting ridge lines of the top surface () and side surfaces () of a cutting insert () have opposing first and second arcuate cutting edges (). One intersecting ridge line of the bottom surface () and side surface () has a third arcuate cutting edge (). The first and third cutting edges are on one side and the second cutting edge is on the other side with respect to the middle line. The length between the first and second cutting edges is greater than the length between the third cutting edge and the other intersecting ridge line (). In a cross section perpendicular to the middle line, the angle formed by the top surface and a line connecting the first and third cutting edges is different from the angle formed by the top surface and a line connecting the second cutting edge and the ridge line ().
