A cutting bit formed as a round plate for a material removal tool has a base body, which is defined by a bottom face, a top opposite it and spaced apart from it, and a side face between them. The side face, with a chip face located on the top, defines a circular cutting edge. For securing the bit, a central opening which can receive a securing screw, for instance, is provided. To secure the cutting bit in a tool body in a manner fixed against relative rotation, a plurality of depressions, for instance, are provided on the top of the cutting bit and can be engaged by a clamping claw supported on the tool body. Circumferential forces engaging the cutting bit are diverted by way of these depressions, thus preventing torsion or twisting of the cutting bit.
