The profile turning tool is used for rough-turning and dressing circumferential and flat surfaces, in particular of workpieces made of light metals. It consists of a holder (10) with a receiver (16) for a diamond cutting head (18) as well as a claw (20), which is embodied as a chip breaker, engages a longitudinal groove (26) in the holder (10) and braces the cutting head (18) by means of a tightening screw (22). The groove (26) is located directly behind the cutting head (18). In longitudinal section, its base has an arcuate, concave shape and represents a pivot bearing for the claw (20) that has a correspondingly shaped underside and is guided on the lateral walls of the groove (26). The tightening screw (22) extends in front of the center of the arc with play through a hole in the claw (20).
