Rotary circular cutting tool consisting of a body (2) of substantially plane and circular shape which is produced from a synthetic material and the centre of which comprises a hub (3) intended to allow the tool to be driven by a drive shaft at a specific rotational speed and the periphery of which comprises a likewise circular ring (10) constituting the actual cutting zone (11,12), characterised in that the fixing of the peripheral ring (10) to the body (2) is carried out: … … - on the one hand, by means of an inner lug (14) parallel to and coplanar with the peripheral ring (10), formed on the inner lateral face (13) of the peripheral ring (10), forming an integral part with the latter and interacting with the body (2) in the region of a complementary groove (8) made on the outer lateral face (7) of the body (2), … - and, on the other hand, by means of radial projections (9) originating from the body (2) and coplanar with the latter and interacting with the lug (14) in the region of recesses (16) defined by periodic interruptions of said lug (14). … …<IMAGE>… |
