A cutter bit (1) with a cutting edge adapted to come into contact with the piece to be machined and a chip-cutter bit (2) superposed with an edge located at least along a portion of its length behind the first cutting edge. The two edges define between themselves a slot (9) giving access to a channel (10) provided in the tool, this channel extending along the length of this slot and being open at at least one of its ends. The tool is particularly useful for machining composite materials comprising fibers embedded in a resin.
