ABSTRACT:
A rotary cutting saw including: (a) a base disk which has a plurality of apertures formed therethrough and opening in axially opposite end surfaces thereof; (b) a plurality of abrasive segments which are fixed to an outer circumferential surface of the base disk; and (c) a plurality of axial-runout restraining members which are received in the apertures. Each of the axial-runout restraining members has a size which is smaller than a size of each of the apertures, such that a clearance is defined between the periphery of each of the apertures and a corresponding one of the axial-runout restraining members which is received in the each of the apertures. A ratio of a size of the clearance to the size of each of the axial-runout restraining members is 5–150%.
