Abstract: The invention relates to a milling cutter which comprises a body (1) having two indentations (4,5) presenting each a housing (4',5') the body of which makes with the longitudinal axis of the body an helix angle which is not equal to zero. In each housing a cutting insert (6,7) is removably fixed which comprises a corner portion emerging on the frontal face (9) of the body and a main or major cutting edge extending beyond along the external lateral rim of the indentation. The shape of this insert and its position on the cutter are such that the radial cutting angle of the cutter varies in decreasing towards the frontal end of the body, and that the clearance angle of the cutter is constant.

Abstract: The milling cutter comprises a body (1) having two indentations (4,5) each presenting a housing (4',5') the body of which makes with the longitudinal axis of the body a helix angle which is not equal to zero. In each housing a cutting insert (6,7) is removably fixed which comprises a tip portion emerging on the frontal face (9) of the body and a main cutting edge extending beyond and along the external lateral rim of the indentation. The position and the shape of this insert are such that the radial cutting angle is not equal to zero and is constant, and that the clearance angle is constant with a wedge angle of the insert which is also constant.

Abstract: The cutting tool, for example a milling-cutter, with interchangeable insert-holding cartridges comprises a body (1) presenting a peripheral supporting face (4) directed towards the rear end of the body and recesses (2) distributed at its peripheral front end and intended to receive interchangeable cartridges (3). Each cartridge comprises at its front end a cutting bit (5), generally fixed in a removable manner, and a back portion (7) at its rear end presenting a supporting face (8) directed towards the front and intended to come, in a service position, in abutment against the supporting face (4) of the body. The fixing devices (9, 11) of the cartridges on the body of the tool are such that they enable an axial setting of the position of said cartridges, as well as the backward movement thereof for a temporary putting out of service.
