A face cutter for machining fiber-reinforced materials such as carbon-fiber-reinforced plastics, glass-fiber-reinforced plastics or plastics reinforced with polyester threads is provided which includes main flutes, which form with trailing premachining lands a cutting wedges with premachining cutting edges, and auxiliary flutes, the number of which corresponds to a number of the main flutes, each trail one of the main flutes in the peripheral sense, each distance in the peripheral sense a postmachining land from the pre-machining land leading in the peripheral sense, and form with the postmachining land a cutting wedge with a postmachining cutting edge. The premachining cutting edges extend alternately with left-hand twist about and untwisted along the tool axis, the postmachining cutting edges trailing the left-hand twisted premachining cutting edges extend untwisted along the tool axis, and the postmachining cutting edges trailing the untwisted premachining cutting edges extend with a left-hand twist about the tool axis. |
