Summary:23xyzxyThere is provided a tool at least partly coated with at least two refractory layers of which one of the said layers is a fine-grained α-AlO-layer which is the top layer along the cutting edge-line and the other a TiCNO- or a ZrCN-layer being the top layer on the clearance face. The coated tool exhibits excellent flank and crater wear and high resistance to flaking, particularly when used for machining of low carbon steel and stainless steel. Used cutting edges can easily be identified by the naked eye.
