Abstract
Abstract Tool comprising a support flange (1) fastened to the end of a drive shaft (2), a grinding wheel (6) which is integral with a metal plate (8) in which it is bonded and molded to shape, and a clamping flange (9) for clamping the plate of the grinding wheel against the support flange. Upon mounting, the plate (7) of the mold and the clamping flange (9) are centered around a collar (12) protruding from the support flange. The plate (7) of the grinding wheel is held in position before clamping by the simple engaging of the edges of two radial notches (14) below the retaining studs (16) of two spindles (15) of the support flange (1). Two locking spindles (19) which are rigidly secured to the clamping flange (9) angularly immobilize the assembly by engagement in two corresponding holes (17) of the support flange.
