Abstract

A metal structure for performing machining operations, in particular a cutting tool (1) for chip removal machine tools, having a first and a second body (2, 3), which extend respectively along a first axis and a second axis (Al, A2 ), which are configured to achieve axial coupling to align the first and second axes (Al, A2) and allow the relative rotation between the first and the second body (2, 3), and a groove (12) having two opposing undercuts (16, 17); and an axial protrusion (20) of a shape substantially complementary to the groove (12); the groove (12) and the axial protrusion (20) being configured in such a way that the relative rotation of the first and of the second body (2, 3) around the first and second mutually aligned axes (Al, A2 ) determines progressive forced coupling with interference between the first and the second body (2, 3) in correspondence with the undercuts (16, 17).
