In an abrasive tool for grinding or polishing, a grippable shaft is connected to an abrasive disc by means of a cylindrical elastic pad of plastic or rubber. A surrounding cap, preferably a screw cap, is provided, which for stiffening the assembly is adapted to be secured at one end to the abrasive disc and is engageable at its other end by means of an annular shoulder to an annular shoulder of the grippable shaft. Alternatively, the grippable shaft may extend through a cylindrical elastic ring of plastic or rubber, which ring is surrounded to a metal sleeve, which is connected to the abrasive disc and adapted to be tightened by a nut so as to stiffen the tool.
