Milling cutter with removable inserts

摘要

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.
