Abstract
A cutting insert includes an insert body; a pair of first surfaces; a through hole extending in a direction of a first axis; a second surface which connects the first surfaces and faces a direction of a second axis orthogonal to the first axis; a third surface which is disposed on the circumferential surface and is connected to the first surfaces and the second surface and faces a direction of a third axis; and cutting edges located at an intersection ridge line between the first surface and the second surface and at an intersection ridge line between the second surface and the third surface. The second surface has a projection part protruding in the direction of the second axis, and as viewed from the direction of the second axis, the through hole and the projection part are disposed to overlap each other.
