Abstract The present invention relates to a coated cutting tool for chipforming machining. The coating includes at least one alumina (Al O ) layer characterized by fine, equiaxed grains. According to the present invention there is provided a body at least partially coated with one or more refractory layers of which at least one layer essentially consist of -AlO. Said -AlOlayer consists of essentially equiaxed grains with an average grain size of <1 m and with a bimodal grain size distribution with coarser grains with an average grainsize in the interval 0.5-1 m and finer grains with an average grainsize of <0.5 m. The AlOlayer further contains striated zones containing titanium (>5 at %) but no nitrogen or carbon. This particular microstructure is obtained by temporarily stopping the gases needed for the growth of the AlOlayer and introducing TiCl.
