The pocket has a raised portion (20) with a flat upper support face (22) to be received in a recess of an insert and support the insert by receiving a bottom surface of the recess bearing on the support face (22). A projecting member (25) of the raised portion (20) has delimiting walls (29) designed to bear against border walls of a said recess of an insert for establishing mutual contact therewith and prevent rotation of the insert in the pocket by receiving a rotational moment acting on the insert in an active chip-removing state of the tool.
