A cutting tool, for example, a saw or a drill bit that is used to cut rock, with a metallic carrier body (2) and cutter segments (1) that are secured to this at intervals, with a preferably metallic bond and diamond as the abrasive grain. The cutter segments (1) are heterogeneous in the direction of rotation. As an example, the quality of the abrasive grain and/or the concentration of the abrasive grain varies within the cutter segments (1) to the length of the cutter segment (1) and/or the size of the abrasive grain is different. Ahead of the actual cutter segment (1) there is a damping layer. (Figure 6).
