Abstract

To support an indexable cutting insert (6a) cutting with an end edge and facing edge (7a) as well as circumferentially, with respect to both axially acting forces as well as radially acting forces, the tool body (1) is formed with an abutment surface (17) to accept radially directed forces against which the insert can be clamped; to accept axially directed forces, a holding screw (25) passing through an opening (22, 23) in the insert is formed with an accurately machined portion (28) fitting into an accurately machined portion (29) of a reception bore (27) for the screw, so that the holding screw, itself, acts as an accurately placed axial support for the insert (6a).
