摘要： A scoring tool (35) for a machine saw (10), wherein the scoring tool (35) is designed to be rotatably driven around an axis of rotation (DV) and has a disk-shaped blade body (310) having flat sides (311, 312) facing away from one another, which has, in its center (ZV) penetrated by the axis of rotation (DV), a machine adapter (315) for releasable fastening on a scorer toolholder (34) of the machine saw (10) and has, on its radial outer circumference (313) with respect to the axis of rotation (DV), a scoring tooth arrangement (300) for introducing a score into a first workpiece surface (WO) of a workpiece (W). The scoring tooth arrangement (300) only has a single scoring tooth (301-304) or at least two scoring teeth (301-304), which have an angular interval (WA) of at least 20° in relation to one another with respect to the axis of rotation (DV).
