Metal cutting turning tool

A turning tool comprising:

• a turning insert and a tool body, the turning insert including opposite facing top and bottom surfaces connected by a circumferential side surface;
• a pocket located in the tool body arranged for receiving the turning insert, the pocket including a bottom support surface and first and second pocket side surfaces, the first and second pocket side surfaces forming an acute angle, wherein the first pocket side surface includes first and second side support surfaces, wherein the second pocket side surface includes third and fourth side support surfaces, wherein a first recess is formed between the first and second side support surfaces, wherein a second recess is formed between the third and fourth side support surfaces, and wherein each recess forms a gap between the circumferential side surface and the respective pocket side surfaces, wherein the turning insert is 180 degree symmetrical or indexable in relation to a central axis thereof, wherein the center axis intersects the top and bottom surfaces, wherein the turning insert includes two opposite nose cutting edges, wherein in a top view the turning insert extends a first distance between said nose cutting edges, and extends a second distance perpendicular to the first distance, and wherein the first distance is greater than the second distance;
• and
• a coupling portion, wherein the coupling portion extends along a coupling axis, the coupling axis defining a longitudinal axis of the turning tool, and wherein a line between the two opposite nose cutting edges forms an angle of 35-55° in relation to the coupling axis, wherein the coupling portion extends along a coupling axis the coupling axis, wherein a distance from the first pocket side surface to the coupling axis is shorter than a distance from the second pocket side surface to the coupling axis, wherein a distance from the coupling portion to the first side support surface is shorter than a distance from the coupling portion to the second side support surface, wherein a distance from the coupling portion to the third side support surface is shorter than a distance from the coupling portion to the fourth side support surface, and wherein the third side support surface is in top view convexly curved by a radius of curvature which is smaller than the radius of curvature of the fourth side support surface.
