ABSTRACT:
An abrading tool for any grinding, lapping, polishing or burnishing purpose (e.g. dental applications) has a rotary holder whose shank can be rotated (e.g. in a chuck connected to a motor) and a plurality of angularly equispaced elongate pieces projecting axially from the holder. The pieces carry abrasive over at least part of their lengths and collectively form a forwardly converging body of revolution about the axis (in a rest position) and the generatrices of this body serve to impact against and abrade the surface to be treated upon rotation of the tool.
