Abstract:
Provided is a surface-coated cutting tool including: a tool body ( 3 ) and a hard coating layer on the tool body ( 3 ). The hard coating layer has an alternate laminate structure of A ( 1 ) and B layers ( 2 ). The A layer ( 1 ) is a Ti and Al complex nitride layer satisfying a compositional formula: (Ti 1-z Al z )N, 0.4≤z≤0.7. The B layer ( 2 ) is a Cr, Al and M complex nitride layer satisfying a compositional formula: (Cr 1-x-y Al x M y )N, 0.03≤x≤0.4 and 0≤y≤0.05. The value of a ratio tB/tA of the average layer thickness of the B layer ( 2 ) to the average layer thickness of the A layer ( 1 ) satisfies 0.67 to 2.0. The lattice constant a(Å) of crystal grains of the hard coating layer satisfies 4.10≤a≤4.20. The ratio of I(200) to I(111) satisfies 2.0≤I(200)/I(111)≤10.

Claim (Index 2):
The surface-coated cutting tool according to  claim 1 , wherein a value of a plastic deformation work ratio W plast /(W plast +W elast ), which is obtained by performing a nanoindentation test at an indentation depth of 1/10 or less of a layer thickness of the B layer, is within a range of 0.35 to 0.50.
