Cutting insert and indexable rotary cutting tool
A cutting insert includes a cutting edge portion, and the cutting edge portion includes a bottom cutting edge forming an arc shape that protrudes toward a front end side in a central axis direction, an outer peripheral cutting edge forming an arc shape that protrudes toward an outside in a radial direction, and a cutting edge of corner that connects an outer end of the bottom cutting edge in the radial direction and a front end of the outer peripheral cutting edge in the central axis direction and forms an arc shape that protrudes toward a front end outer circumferential side. The bottom cutting edge and the outer peripheral cutting edge are formed so as to form a linearly symmetric shape together with respect to an imaginary straight line that passes through an arc central point of the cutting edge of corner and intersects the central axis.
