摘要：
The present invention relates to a coated cutting tool for chip forming machining of metals comprising a substrate having a surface coated with a chemical vapour deposition (CVD) coating. The coated cutting tool comprises a substrate coated with a coating comprising a layer of ±-Al 2 O 3 , wherein said ±-Al 2 O 3 layer exhibits a dielectric loss of 10 -6 ‰¤tan´‰¤0.0025, as measured with AC at 10 kHz, 100 mV at room temperature of 20°C.
