Grinding saw blade and combined saw blade

The utility model relates to the technical field of saw blades, in particular to a grinding saw blade and a combined saw blade, the grinding saw blade comprises a base disc and a grinding part, the grinding part is fixedly arranged on the peripheral face of the base disc in the circumferential direction of the base disc, the grinding part is flush with one side face of the base disc in the axial direction of the base disc, and the grinding part and the other side face of the base disc in the axial direction of the base disc define a groove. When the grinding saw blade and the cutting saw blade are overlapped, the end face, flush with the grinding part, of the base disc in the grinding saw blade abuts against the cutting saw blade. According to the arrangement, a gap between the grinding saw blade and the cutting saw blade can be avoided, cuttings are prevented from entering the space between the grinding saw blade and the cutting saw blade, then the working stability of the combined saw blade can be improved,
