Abstract
A saw blade having two or three blade members immovably coupled to each other, and having a plurality of coolant passages grooved on the interior of the blade members. The passages communicate with coolant inlet ports and terminate at openings located at the root peripheral side of the blade cutting edges. The saw blade releases coolant from itself which not only cools the blade members but also blows cut material from the blade cutting edges thereby facilitating a cutting operation being performed on a workpiece. The saw blade may be utilized with a coolant feeding apparatus, having distributors which are rotatably driven and connected with stationary feeding pipes, the pipes having axial channels communicating with the coolant inlet ports of the saw blade.
