<p>A surface coated cutting tool having, on a surface of a substrate, a hard coating layer including at least an aluminium oxide layer, the surface having a rake face on a main face thereof and a flank on a side face thereof, wherein, when a value calculated by the following equation (I) is a texture coefficient TC of the (HKL) plane of the aluminium oxide layer, a ratio of a texture coefficient TC R on the rake face to a texture coefficient TC F on the flank, TC F /TC R , is in a range of 0.3 to 0.95. TC = I HKL / I o HKL 1 / 6 �¢ £ I hkl / I 0 ( hkl ) where I(HKL), I 0 (HKL), and £[I(hkl)/I 0 (hkl)] are as described in the specification.</p> |
