Under such cutting conditions, the conventional surface-coated cutting tools described above cannot satisfactorily cope with these conditions because the adhesion of the (Ti, Al)N coating layer to the substrate surface is insufficient. be.

After specifying the base material as WCC cemented carbide or TiCN-based cermet, the above-mentioned wear-resistant material is coated on the surface of the base material with a titanium nitride (hereinafter referred to as TiN) coating layer formed by physical vapor deposition.

)N coating layer is formed, the adhesion of the TiN coating layer to the substrate and the (Ti, Al)N coating layer is extremely high.

The research results showed that.

するものである。This invention was made based on the above research results, and includes adhesive physical vapor deposition of TiN with an average layer thickness of 01 to 1 μm on the surface of a base made of WCC cemented carbide or TiCN-based cermet. A wear-resistant physical vapor deposition coating layer made of (Ti, Ajl')N with an average layer thickness of 0.5 to 5 μm is formed via the coating layer, and if necessary, a wear-resistant physical vapor deposition coating layer of (Ti, Ajl')N with an average layer thickness of ．．
The cutting tool is characterized by a surface-coated cermet cutting tool formed by forming a chipping-resistant physical vapor deposition coating layer of TiN with a diameter of 1 to 3 μm.
つぎに、この発明の切削工具において、これを構成する
被覆層の平均層厚を上記の通りに限定した理由を説明す
る。Next, in the cutting tool of the present invention, the reason why the average layer thickness of the coating layer constituting the cutting tool is limited as described above will be explained.

と定めた。(a) Adhesive Physical Vapor Deposition Coating Layer This TiN coating layer includes a substrate and (Ti,
It firmly bonds to the A7-N coating layer and has the effect of preventing the peeling of the A7-N coating layer even under severe cutting conditions (Ti, A7-N coating layer, but if the average layer thickness is less than 0.1 μm, the above effect will not occur). The desired effect cannot be obtained, and on the other hand, even if the average layer thickness exceeds 1 μm, further improvement effects cannot be obtained due to the above action.
It was determined that
（ｂ） 耐摩耗性物理蒸着被覆層
この（Ｔｉ、Ａｌ）Ｎ被覆層は、きわめて硬質であり、

耐摩耗性を確保することができず、一方その平均層厚が
５μｍを越えると、チッピング（微小欠け）が発生し易
くなることから、その平均層厚を０５〜５μｍと定めた
。(b) Abrasion-resistant physical vapor deposition coating layer This (Ti, Al)N coating layer is extremely hard;
The formation of this layer significantly improves wear resistance, but if the average layer thickness is less than 0.5 μm, the desired excellent wear resistance cannot be achieved, whereas if the average layer thickness exceeds 5 μm, Since chipping (micro-chips) is likely to occur, the average layer thickness was set at 0.5 to 5 μm.
なお、（Ｔｉ、Ａｌ）Ｎを組成式・ （Ｔ ＋ ＸＡ

か進行するようになるという理由によるものである。In addition, (Ti, Al)N is represented by the composition formula: (T + XA
l + −X ) N, the value of X is 025
The value of X is preferably 0.95 to 0.95, because if the value of This is because if the temperature exceeds 100%, the high-temperature oxidation resistance decreases, and especially the flank wear of the cutting edge progresses.

平均層厚を０．１〜３μｍと定めた。(c) Fracture-resistant physical vapor deposition coating layer The TiN coating layer formed as the outermost layer has the effect of improving the fracture resistance of the cutting edge, so it is formed as necessary, but the average layer thickness is less than 0.1 μm. However, even if the average layer thickness exceeds 3 μm, the effect of further improving the fracture resistance does not appear. Therefore, the average layer thickness is set at 0.1 to 3 μm. Ta.
