In a side view, the cutting edge inclines upward with respect to a reference plane perpendicular to the center axis of the cutting insert, starting from the flat cutting edge toward the main cutting edge, until a top section is reached, whereupon the cutting edge inclines downward with respect to the reference plane, and the outer peripheral cutting edge angle of the auxiliary cutting edge is larger than the outer peripheral cutting edge angle of the main cutting edge.
