Abstract in different language:	Modern additive manufacturing (AM) processes allow us to create parts of fairly high precision and various shapes with diverse internal features. These possibilities are, for example, often used when designing the conformally cooled parts of injection moulds. However, this research is focused on applying an additive approach to the design and manufacturing of a standard CCMT indexable insert to improve tool life when turning Inconel 718. Machining materials such as Inconel or titanium alloys requires intensive cooling of the cutting edge to maximize the tool life. The system proposed in this paper delivers a precisely directed coolant through internal channels in the indexable insert and its holder to the cutting edge from the rake face as well as the flank face of the insert. This has a significant positive influence on the life of the tool when machining Inconel 718 and other superalloys. This paper provides an extensive overview of the problem and then proposes three possible approaches to manufacture said indexable insert. They are additive manufacturing out of tungsten carbide, AM out of steel and brazing cutting edge out of tungsten carbide or CBN and AM out of tool steel and thermally spraying a wear resistant layer
