Tool life tests were conducted for grade 60 of nodular cast iron with carbide and ceramic cutting tools, and the result was compared with that for grades 80 and 100. It was found that ribbon type flank build-up or smear protects the flank of carbide tool from flank wear. Tool life for grade 60 of nodular cast iron was much longer than that for grades 80 and 100. Cast iron cutting grade carbide showed better tool life than steel cutting grade carbide when machining nodular cast irons. Tool life for ceramic tool was longer than that for carbides, especially at high speeds because of steep slope of tool life diagram for ceramic tool. The wear process of carbide and ceramic tools was investigated together with the variation of tool forces due to flank wear.
