Abstract: An improved abrading disk tool for holding a multi-layer brush of stacked non-woven fibrous webs to be mounted on a rotation driving spindle in use, which tool can be easily assembled without using any adhesive, but using tool members which, preferably, may be injection-molded with a plastic material. The members of the tool include a pair of compatible holder halves (1), each having a base (10) and a central hollow pole (20) and/or a plurality of eccentrically arranged hollow and/or solid poles (30) axially extending from the base. The holder halves have corresponding configurations, preferably geometrically dimensionally equal ones. Each pole has snap detent means comprising a male element (40) and/or a female element (50), provided at its free end, which element is engageable with that of a corresponding pole in the counterpart holder half to axially inter-lock both the holder halves.
