Abstract

According to the subject matter of the present application there is provided a reversible cutting insert(1200) comprising top face(1210T), a bottom face(1210B), at least one side wall (1212 ) extending therebetween. The cutting insert (1200) is further formed with a central bore(1216)e having a central axis X, the central bore (1216) extending between the top face (1210T) and the bottom face (1210B). The central bore (1216) is formed with at least a first inner surface (1220) and a second inner surface (1230), each extending between the top face (1210T) and the bottom face (1210B). Each of the first and the second surface has a respective first (1222T) and second(1232T) top rim at the top face (1216T) and a respective first (1222B) and second (1232B) bottom rim at the bottom face (1210B). The maximal distance R1 between the first bottom ri (1222B) and the central axis X is greater than maximal distance r2 between the first top rim (1222T) and the central axis X, and the maximal distance R2 from the central axis X of the second top rim (1232T) is greater than the maximal distance r2 between the second bottom rim (1232B) and the central axis X.
