There has been a great interest for improving the machining of cast iron materials in theautomotive and other industries. Comparative studies for tool used to machine grey cast iron (CI)and compacted graphite iron (CGI) on dry machining were also performed in order to find out whyin this case the tool lifetime is not significantly higher. However the machining these materialswhile considering turning with the traditional high-speed steel and carbide cutting tools present anydisadvantages. One of these disadvantages is that all the traditional machining processes involve thecooling fluid to remove the heat generated on workpiece due to friction during cutting. This paperpresent a new generation of ceramic cutting tool exhibiting improved properties and importantadvances in machining CI and CGI. The tool performance was analyzed in function of flank wear,temperature and roughness, while can be observed that main effects were found for tool wear, wereabrasion to CI and inter-diffusion of constituting elements between tool and CGI, causing crater.However the difference in tool lifetime can be explained by the formation of a MnS layer on thetool surface in the case of grey CI. This layer is missing in the case of CGI
