ABSTRACT:
In a rotary cutting tool for use with at least one cutting insert, a cutter body is rotatable about a rotational axis. The cutting insert is mounted to an outer periphery of a forward end of the cutter body. A chip moving unit is arranged outwardly of an outer peripheral surface of the cutter body for moving chips generated by the cutting insert, to a desirable location. A cover assembly is provided for covering the outer peripheral surface of the cutter body, having a flow passageway defined between an inner peripheral surface of the cover assembly and the outer peripheral surface of the cutter body. An air sending assembly is arranged within the flow passageway for sending air adjacent the cutting insert, toward the desirable location during rotation of the cutter body about the rotational axis.
