Production, properties and application examples of diamond coated tools are presented. The state of development of cBN-coatings for tools is mentioned. DLC (diamond like carbon) coatings are explained in comparison to diamond coatings. Diamond coatings can be used for the cutting of difficult-to-machine materials, like high-strength alloys or ceramics. A wide range of tool geometries is coatable, including micro tools with diameters down to 50 mu m. Diamond coatings can be produced with a roughness, that makes grinding possible. cBN-coatings are not yet able to withstand cutting processes. The film thickness has to be increased. DLC-coatings are mainly used for pressing and forming tools, but cutting is possible with some kinds of DLC-coatings.
