Abstract of the Disclosure The present invention relates generally to metal-cutting practice and, more specifically, to rotary cutting tools. The proposed cutting tool comprises a holder, wherein a working head is rotatably mounted. The working head carries at least one edge having a cutting lip which is defined by inter- secting of its face and relief surfaces. The cutting tool incorporates a chip-breaking device which, according to the invention, is essentially a plate made fast on the holder at an angle to the face surface of the edge, thus providing for chip disposal from the cutting zone and arranged in such a manner that one of its edges crosses the cutting lip of the tool edge and is located as close as possible to the edge face surface, provision being made for the working head to freely rotate, The invention can find most utility when applied for machining ductile metals and alloys to form flow chip. The invention can also be used for machining plastics and some elastic nonmetallic materials. The rotary cutting tool of the envention ensures high- -quality machining and provides for a directional chip disposal beyond the cutting zone.
