In order to examine the possibility of composite-gradient ceramics tool using the wet-shaping process, simultaneous slip casting and time lag slip casting are proposed to alumina and alumina + zirconia slip. The result which compared the sintered ceramics was produced from both processes, in the time lag slip casting, the pores were not observed at the near of interface between alumina and alumina + zirconia layer and the zirconia particles were not distributed in the alumina layer. Therefore, using the time lag slip casting, a trial product cutting tool was produced at alumina + zirconia layer on the cutting surface, and alumina layer to the base material. From the result of a cutting test, the life of a trial production tool was shown that were 10 min at a cutting speed of 50.9m/min in the S55C steel. At this time, the wear type of trial production tool was the flank wear similar to the commercial tools. Considering from the results, the possibilities of proposing process have been confirmed sintering properties of a composite-gradient ceramics and wear type of a trial production tool.
