COATED SURFACE CUTTING TOOL AND MANUFACTURING METHOD THEREFOR

摘要

This coated surface cutting tool comprises a base material and a coating formed on the base material and is characterized in that: the coating comprises at least one TiB2 layer; and for said TiB2 layer, TC(100) in the orientation index TC(hkl) is maximal or the ratio I(100)/I(101) of the X-ray diffraction intensity of the (100) surface, I(100), to the X-ray diffraction intensity of the (101) surface, I(101), is 1.2 or more.
