Abstract
A cutting tool has a chip breaker, disposed in the region of the chip face, for preventing uncontrolled chip formation. The chip breaker is disposed at a certain spacing from the cutting edge of a diamond layer that is applied to a substrate body. In prior art versions, a joint remained between the chip breaker and the diamond layer, and chips could penetrate the joint and become stuck there. To prevent this, the diamond layer, in the region of the chip breaker, is recessed down to the substrate body and that the chip breaker is applied there directly to the substrate body. In this way, a chip breaker can be disposed with a good hold in the vicinity of the cutting edges without sacrifices in terms of the strength of the cutting layer.
