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 ). |
