The invention relates to a composite system for a cut-off wheel ( 1 ), in particular with a diameter greater than 400 mm, consisting of an abrasive external cutting ring with depressions ( 3 ) on both sides in the vicinity of the bore, two flush-fitting tensioning plates ( 2 ) being placed in said depressions to act as a core clamping device. Said clamping plates are reusable elements, retained by the user, and transfer forces to the clamping flanges ( 4 a +4 b) of the machine. The plates also increase stability and reduce waste.
