Rotary cutting tool, in particular for high speed machining with nano-lubrication. The lubricant is fed to the end surface of the cutting part (12) of the tool through a central lubrication channel (22) drilled along the axis of rotation (10) of the tool, with one non-through end, located just near the end surface, which is connected to the latter by secondary channels (24) opening near each end cutting edge (20). Cutting parameters relating, in particular, to the end dedendum angle, the width of end clearance and the width of the circular land of each cutting edge further improve the quality of the work carried out.
