The invention relates to a tool system for metal-cutting machining of sheetlike workpieces (12). The forming of a notch in the surface of the workpiece is often advantages in order to facilitate the banding of the metal sheet along the line of the notch. In order to avoid time consuming changeover operations cause by the use of for instance a planing machine it is proposed that a cutting tool (20, 24) is disposed in at least one tool holder (14) of a turret-type stamping or punching machine which has drive means (56), with the aid of which the work piece (12) is moveable in its extension plane, which cutting tool is adjustable, perpendicular to the extension pane of the workpiece (12) to a certain machining position with the aid of feed means (38).
