The proposed cutting tool comprises a holder, wherein a working head is rotatably mounted. The working head carries at least one edge whose cutting lip is defined by intersecting of its face and relief surfaces. The cutting tool incorporates a chip-breaking device, according to the invention, which is essentially a plate made fast on the holder at an angle to the face surface of the edge to provide 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. |
