The coolant conveying member includes a member body having a fluid passage formed therein, and a nozzle to convey and to jet out the coolant fluid therethrough. The nozzle is shiftable relative to the member body, between a first, extended position and a second, retracted position. In the extended position, for example, assumed during the cutting operation—the nozzle extends out and forwardly from the member body, stabilized by the continuous flow of coolant fluid therethrough, forcing the nozzle forwardly. In the retracted position, for example, assumed when the when the coolant fluid does not flow through the coolant conveying member, or flows at a very low rate, the nozzle may be at least partially accommodated in the fluid passage, to allow, for example, indexing or replacing of the cutting insert. ## Claims ### Claim 1 A cutting tool (10), comprising: a shank portion (18);
