A cutting insert comprising: opposing top and bottom end faces (24, 26) and first and second side surfaces (28A, 28B) extending therebetween; a corner surface connecting the first and second side surfaces (28A, 28B) and intersecting the top end face to form a corner cutting edge; a cutting corner, located on the top end face adjacent the corner cutting edge, the cutting corner having a bisector; and a chip-control arrangement located at the cutting corner and comprising: a projection protruding from the top end face and extending longitudinally in a direction transverse to, and to opposites sides of, the bisector, the projection comprising two opposing projection extremities (46A, 46B) and an elongated surface extending therebetween, the elongated surface inclining upwardly from the top end face in a direction away from the corner cutting edge; and a protrusion protruding from the top end face and comprising a protrusion ridge that extends longitudinally lengthwise along the bisector, from the elongated surface in a direction towards the corner cutting edge; wherein the protrusion is lower than the projection, in relation to the upward direction (D U); characterised in that in a cross-sectional view taken in a plane along, and through, a longitudinal extension of the protrusion ridge, the protrusion ridge is concavely curved; and in a top view of the cutting corner, the projection extends longitudinally in a direction perpendicular to the bisector; and the projection further comprises a declining surface extending between the two projection extremities (46A, 46B) and declining from the elongated surface in a direction away from the corner cutting edge. opposing top and bottom end faces (24, 26) and first and second side surfaces (28A, 28B) extending therebetween;
