ABSTRACT:
A device is disclosed for forming axial grooves in cylindrical workpieces. The device includes a first tool part having a receiver for the workpiece, and at least one lever pivotably mounted within the first tool part. The lever supports a grooving tool provided with a cutting edge facing the receiver. The lever also has a first bearing or supporting surface on the side opposite the cutting edge, against which one end of a clamping bolt abuts. The clamping bolt is driven by a second tool part rotatably supported on the first tool part so that it can pivot around the receiver axis.
