Prescoring tool for a sawing machine

A scoring tool for a machine saw, in the form of a handheld machine saw or a semi-stationary machine saw, or as a component of this machine saw, wherein the scoring tool is designed to be rotatably driven around an axis of rotation and has a disk-shaped blade body having flat sides facing away from one another, which has, in its center penetrated by the axis of rotation, a machine adapter for releasable fastening on a scorer toolholder of the machine saw and has, on its radial outer circumference with respect to the axis of rotation, a scoring tooth arrangement for introducing a score into a first workpiece surface of a workpiece, wherein the scoring tooth arrangement has at least one main cutting edge extending transversely to the flat sides for producing a score base of the score and has secondary cutting edges on sides opposite to one another with respect to the at least one main cutting edge transversely to the at least one main cutting edge for producing score side flanks of the score-ERR wherein end regions of the secondary cutting edges on the radial inside with respect to the axis of rotation and provided for cutting the score into the workpiece have a radial distance to the radial outer circumference of the scoring tool such that scores of different depths are producible using the scoring tool up to a maximum depth delimited by the radial distance, and the machine saw can introduce, by means of a saw tool, a saw cut aligned with the score from a second workpiece surface of the workpiece opposite to the first workpiece surface having a saw cut width of the saw cut less than a score width of the score into the workpiece, so that the workpiece does not tear out at the score side flanks, characterized in that and wherein the scoring tooth arrangement only has a single scoring tooth or at least two scoring teeth, which have an angular interval of at least 20° in relation to one another with respect to the axis of rotation.
