And at (Ti, Al) N layer and as the CrB on upper strata as lower floor
2Have the occasion of close binder between the layer, if its average bed thickness less than 0.1 μ m, then can't guarantee between upper strata and lower floor, to have firm bond strength, on the other hand, if its average bed thickness surpasses 0.5 μ m, then the intensity of hard coating can reduce at the close binder place, and this will become the reason that tipping takes place, therefore, its average bed thickness is advisable with 0.1～0.5 μ m.

1-X, Al
X-Y, Si
Y) N) or (Ti, Al, B) N layer (composition formula: (Ti
1-X, Al
X-Z, B
Z) N) and occasion, thereby, a part of Al make Si composition or B composition and Al coexistence improve hear resistance and high temperature hardness by being replaced with Si or B, but, if the Z value conduct of the ratio of the Y value of the ratio of expression Si or expression B with the total amount of Ti and Al in shared ratio and above 0.10, then elevated temperature strength will reduce, therefore, Y value and Z value are to be advisable below 0.10.
As surface-coated cutting tool of the present invention, it constitutes (the Ti of the lower floor of hard coating, Al) N layer, (Ti, Al, Si) N layer or (Ti, Al, B) the N layer has excellent high temperature hardness and hear resistance and has excellent elevated temperature strength, and can guarantee and be cut the heat endurance (extremely low reactivity) that has excellence between the material by CrB2 layer as the upper strata, therefore, even if the machining of hard hard-cutting material is carried out to be accompanied by the high speed that produces golf calorific value, also can bring into play excellent mar proof for a long time.
