The utility model relates to the technical field of cutting tools, in particular to a milling blade and a milling tool. The milling blade comprises a blade body, and the blade body comprises a first surface located on one side of the blade body and a second surface located on the other side of the blade body; the second surface is positioned on the other side of the blade body and is opposite to the first surface; the plurality of side surfaces are used for connecting the first surface and the second surface; and the mounting hole penetrates through the blade body, so that the first surface is communicated with the second surface. The side face of the milling blade is provided with the groove part, the main cutting edge is divided into the multiple separated sub cutting edges by the groove part, the length of the cutting edge making contact with a workpiece is reduced during machining, and the cutting force and machining vibration are effectively reduced. Meanwhile, the rake angle alpha of each sub-cutting ed
