Abstract
A coated cutting tool for chip forming machining of metals includes a substrate having a surface coated with a chemical vapour deposition (CVD) coating. The coated cutting tool has a substrate coated with a coating including a layer of α-Al2O3, wherein the α-Al2O3 layer exhibits a dielectric loss of 10−6≤tan δ≤0.0025, as measured with AC at 10 kHz, 100 mV at room temperature of 20° C.
