According to the subject matter of the present application there is provided a reversible cutting insert comprising top face, a bottom face, at least one side wall extending therebetween. The cutting insert is further formed with a central bore having a central axis X, the central bore extending between the top face and the bottom face. The central bore is formed with at least a first inner surface and a second inner surface, each extending between the top face and the bottom face. Each of the first and the second surface has a respective first and second top rim at the top face and a respective first and second bottom rim at the bottom face. The maximal distance R1 between the first bottom rim and the central axis X is greater than the maximal distance r1 between the first top rim and the central axis X, and the maximal distance R2 from the central axis X of the second top rim is greater than the maximal distance r2 between the second bottom rim and the central axis X. |
