The groove extends from a first end part closest to the cutting edge to a second end part most away from the cutting edge. The groove includes an opening and a bottom surface. An angle θ2 formed by the bottom surface and a raised surface extended from the bottom surface toward the first end part is 95-135°. A cutting tool includes a holder, which has a length extending from a first end to a second end and includes a pocket located on a side of the first end, and the insert located in the pocket.
