Abstract
The invention relates to a tool (7B) comprising a cutting edge (24) that is located at the junction between a rake face and a flank face (23), said rake face having a front facet (26) that is intended to be moved transversely to the relative direction of movement (29, 30) between the piece (2) and the tool (7B) during machining operations and an inclined facet (27) that is disposed between the front facet (26) and the flank face (23). The above-mentioned cutting edge (24) is located at the junction between the inclined facet (27) of the rake face and the flank face (23).
