Hard alloy circular saw blade

The utility model relates to the technical field of cutting equipment, in particular to a hard alloy circular saw blade which comprises a saw blade body, a center hole is formed in the middle of the saw blade body, a plurality of saw teeth are evenly arranged on the peripheral face of the saw blade body, and a chip containing groove is formed between every two adjacent saw teeth. A blade is embedded in the edge of the side face of the chip containing groove of the saw blade body. Protruding parts are arranged on the side faces, away from the saw blade body, of the sawteeth. According to the circular saw blade, due to the arrangement of the protruding parts, when equipment provided with the circular saw blade is applied, the cutting stress area of a single blade and a cut object is reduced when the single blade cuts a workpiece, then the cutting amount of the blade when the blade cuts the workpiece is limited, the blade can be protected when a hard tree knot or too large pushing force is encountered when wood
