A circular saw blade is disclosed which includes a circular body having two side faces, a central bore, and a toothed peripheral edge. Disposed within the body of the saw blade is a plurality of circumferentially extending laser-cut slots. Each of the slots consists of an arc of a circle concentric with the body of the saw blade and parallel to the peripheral edge thereof. The slots extend through the body from one side face to the other, and are spaced in a manner such that each slot cools an area of the body when the saw blade is in operation.
