A cutting insert for a milling tool, the cutting insert comprising an insert body having a central longitudinal axis extending along a longitudinal direction of the insert body and an imaginary centre plane comprising the central longitudinal axis, the insert body being generally defined by a top surface, a bottom surface, and a circumferential surface extending between the top surface and the bottom surface, the top and bottom surfaces (10, 12) extending substantially in the longitudinal direction on opposite sides of the centre plane, wherein the insert body at the top surface comprises a first rake face and the bottom surface comprises a second rake face wherein the insert body at the circumferential surface comprises a first radial side and a second radial side extending in the longitudinal direction on opposite sides of the insert body, and a first axial side and a second axial side extending across the longitudinal direction on opposite sides of the insert body, wherein the first axial side comprises a first relief face, a second relief face, and a first recess, the first relief face extending along the first rake face and the second relief face extending along the second rake face, wherein the first recess extends between the first and second relief faces (22a, 22b) and comprises a first bottom surface, and wherein the insert body further comprises at least a first cutting edge, the first cutting edge extending along a rim portion at an intersection between the first rake face and both the first radial side and the first axial side, characterized in that the first relief face, the second relief face, and the first recess are arranged such that each point of the first relief face, the second relief face, and the first recess is visible from either a first side view towards the first radial side or from a second side view towards the second radial side, and such that the insert body is longer along the longitudinal direction at a central portion towards the central longitudinal axis than at an outer portion towards one of the first or second radial sides (18a, 18b). wherein the insert body at the top surface comprises a first rake face and the bottom surface comprises a second rake face wherein the insert body at the circumferential surface comprises a first radial side and a second radial side extending in the longitudinal direction on opposite sides of the insert body, and a first axial side and a second axial side extending across the longitudinal direction on opposite sides of the insert body, wherein the first axial side comprises a first relief face, a second relief face, and a first recess, the first relief face extending along the first rake face and the second relief face extending along the second rake face, wherein the first recess extends between the first and second relief faces (22a, 22b) and comprises a first bottom surface, and wherein the insert body further comprises at least a first cutting edge, the first cutting edge extending along a rim portion at an intersection between the first rake face and both the first radial side and the first axial side, characterized in that the first relief face, the second relief face, and the first recess are arranged such that each point of the first relief face, the second relief face, and the first recess is visible from either a first side view towards the first radial side or from a second side view towards the second radial side, and such that the insert body is longer along the longitudinal direction at a central portion towards the central longitudinal axis than at an outer portion towards one of the first or second radial sides (18a, 18b).
