A ventilating insert for the substantially coaxial fixing of abrasive tools, such as deburring wheels, cutting wheels, fiber discs, Scotch-Brite® discs or tools which can otherwise be related to an abrasive disk-like element (2), to the free end (3) of a rotating shaft (4) of a grinder, which comprises:
at least one threaded ring (9) for coupling to the free end (3) of the rotating shaft (4), an annular portion (10) of which is jointly associated with the disk-like element (2), the threaded ring (9) comprising a central threaded hole (12) and being designed to be arranged substantially coaxially with the disk-like element (2) and able to be associated with corresponding threaded means (13) provided on the free end (3) of the rotating shaft (4). The ventilating insert comprises means for deflecting at least one fluid for cooling the disk-like element (2) which are associated with the threaded ring (9) for propelling radially the cooling fluid from the central region to the peripheral region of the disk-like element (2) during the rotation thereof.
