A turning tool for metal cutting comprising - a tool body, which has a tool body top surface, and which comprises, - arranged at a front end in the tool body top surface, an insert seat for receiving a cutting insert, and - a tool body bore that is spaced apart from the insert seat and extends downward from an opening in the tool body top surface, - a clamping member, which is arranged at the tool body top surface, and which comprises - a base body, which has - a base body top surface, and a base body bottom surface facing the tool body top surface, and - a clamping member through hole, which extends from an opening in the base body top surface to an opening in the base body bottom surface, and which is aligned with the tool body bore, - and a clamping arm, which protrudes from the base body and extends at least a portion over the insert seat, and - a clamping pin, which connects the tool body and the clamping member, and which comprises - a longitudinal shaft that has a longitudinal axis and that extends through the clamping member through hole and into the tool body bore, wherein the shaft is axially movably received in the tool body bore and operable to move to a first axial position, - a head at an upper end of the shaft, and - a coolant fluid channel having a first outlet opening in the head, wherein the clamping pin is configured to, in the first axial position, engage the base body and force the base body, together with the protruding clamping arm, toward the tool body top surface, whereby, when a cutting insert is received in the insert seat, the cutting insert is clamped in the insert seat, characterized in that, - in the first axial position, the first outlet opening in the head is located above the base body top surface, - the shaft is axially movably received in the tool body bore by being axially slidable, and in that - the turning tool further comprises a locking mechanism, which is configured to, in the first axial position, releasably lock the shaft in the tool body bore against at least axial sliding toward the tool body top surface. -
