A tool for a coal cutting, mining or road cutting machine, having a round-shaft cutter with a cutter head and a cutter shaft. A wear-protection disk is pushed on the cutter shaft, on an upper side of which the cutter head rests. The cutter shaft is captively held in a receiver of a holding projection of a cutter holder in a direction of a center longitudinal axis of the projection but freely rotatable around the center longitudinal axis. The projection has a support surface which extends at least in sections around the receiver on which a wear-protection disk rests with an opposite surface and is supported on a support surface of the cutter holder. The cutter head rests on the upper side of the wear-protection element facing away from the support surface. In order to better protect the cutter holder of such a tool against wear effects, the support surface extends transversely with respect to the center longitudinal axis of the receiver up to exterior dimensional limits of the area of the holding projection adjoining the support surface. The wear-protection disk covers the entire, radially outwardly located area of the support surface with its opposite face.
