    摘要: A surface coated cutting tool with a high level of both wear resistance and defect resistance in balance is provided. The surface coated cutting tool of the present invention includes a base material, and a coat film formed on the base material. The coat film includes at least one titanium carbonitride layer. The titanium carbonitride layer has a maximum value for an orientational index TC (220) among texture coefficients TC (hkl). When an indentation hardness of a standard block for hardness is Hs and an indentation hardness of the titanium carbonitride layer is Ht, the average value of the relative hardness Ht/Hs for a plurality of times of measurement is greater than or equal to 3. The difference between the maximum value Htmax/Hs and minimum value Htmin/Hs of the relative hardness of the titanium carbonitride layer to the relative hardness Ht/Hs is less than or equal to 0.5.

    摘要: A surface-coated cutting tool having excellent abrasion resistance and defect resistance is provided. The surface-coated cutting tool includes a substrate and a covering layer, wherein the covering layer includes one or two or more sublayers, a thickness T1 of a portion of the covering layer having the smallest thickness in a cutting edge line portion and a thickness T2 of the covering layer at a point 1 mm away from a cutting edge line in a rake face direction in a cross section cut by a particular plane satisfy T1

    摘要: A surface-coated cutting tool excellent in wear resistance is provided. The surface-coated cutting tool of the present invention includes a base material and a coating formed on the base material. The coating includes an inner layer and an outer layer. The inner layer is a single layer or a multilayer stack constituted of two or more layers made of at least one element selected from the group consisting of group IVa elements, group Va elements, group VIa elements in the periodic table, Al, and Si, or a compound of at least one element selected from this group and at least one element selected from the group consisting of carbon, nitrogen, oxygen, and boron. The outer layer includes α-aluminum oxide as a main component and exhibits an equivalent peak intensity PR(024) of a (024) plane of x-ray diffraction of larger than 1.3.
