摘要： Wear resistance and chipping resistance are both highly established for a surface-coated cutting tool (1). The surface-coated cutting tool (1) of the present invention includes a base material (7), and a coat film formed on the base material (7). A first coat layer (8) at a chamfer portion (4) has residual stress that exhibits a minimal value at a depth A within 2 µm from the surface, and that is greater than or equal to -7 GPa and less than or equal to -1 GPa. The first coat layer(8) at a portion other than the chamfer portion (4) has residual stress that increases continuously or stepwise as a function of advance in the central direction of the rake face and the central direction of the flank face, and that is greater than or equal to 0 GPa and less than or equal to 2 GPa. In the first coat layer (8), the region further deeper in the depth direction from depth A at the chamfer portion and the region other than the chamfer portion (4) is a rough crystal texture region (9) including crystals larger than the crystals in a fine crystal texture region (10).

摘要： A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an ±-Al 2 O 3 layer (1). The ±-Al 2 O 3 layer (1) contains ±-Al 2 O 3 crystal grains and sulfur, and has a TC(006) of more than 5 in texture coefficient TC(hkl). The sulfur has a concentration distribution in which a concentration of the sulfur decreases in a direction away from a base-material-side surface of the ±-Al 2 O 3 layer, in a thickness direction of the ±-Al 2 O 3 layer.

摘要： A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an ±-Al 2 O 3 layer containing a plurality of ±-Al 2 O 3 crystal grains. The ±-Al 2 O 3 layer includes: a first region made up of an edge ridgeline, a region A of a rake face, and a region B of a flank face; a second region which is a region of the rake face except for the region A and covered with the coating; and a third region which is a region of the flank face except for the region B. The region A is sandwiched between the edge ridgeline and a virtual line in the rake face, the virtual line passing through a point located 1 mm away from the edge ridgeline and extending along the edge ridgeline. The region B is sandwiched between the edge ridgeline and a virtual line in the flank face, the virtual line passing through a point located 1 mm away from the edge ridgeline and extending along the edge ridgeline. The ±-Al 2 O 3 layer satisfies a relation b-a > 0.5, where a is an average value of a TC(006) in the first region in texture coefficient TC(hkl) and b is an average value of the TC(006) in the second region or the third region in texture coefficient TC(hkl).
