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.
