Abstract
A tool for a coal cutting, mining or road cutting machine, having a round-shaft cutter with a cutter head and a cutter shaft. The cutter head rests on a wear-protection disk having an opening. The cutter shaft passes through the opening and the cutter shaft has a clamping element which maintains the round-shaft cutter captively but rotatable around a center longitudinal axis of the receiver, in a receiver of the cutter holder. For a cost-effective fixation of the wear-protection disk against relative rotation, the wear-protective disk has a tab formed on it, which is designed as a holding element and is bent in a direction toward the cutter holder, and which is interlockingly fixed in place in the circumferential direction of the wear-protection disk on a stop of the cutter holder. In one embodiment, the wear-protection disk is fastened on the clamping sleeve.
