A wheel cutter blade has a plurality of blade bodies affixed around the periphery of a blade base plate. The inner peripheral portion of each blade body is joined to the blade base plate. The peripheral portion of each blade body also joins to the peripheral portion of the adjacent blade bodies, such that the blade bodies form a consolidated annular molded body. Each blade body contains grinding granules only at the outer peripheral portions of each blade body, so that the grinding granules are not in contact with the blade base plate. The blade bodies may have shallow surface groove channels on the front and rear sides of each blade body, such that an air flow is created. This air flow is useful to reduce friction heat and exhaust ground dust.
