Compound tool and machine tool

The utility model relates to a compound cutter and a machine tool, the cutter comprises a cutter handle, a cutter bar, a far-end blade and a near-end blade, the cutter handle is fixedly connected with the cutter bar, the far-end blade and the near-end blade are detachably fixed to the cutter bar, the near-end blade is located between the far-end blade and the cutter handle, and the radius size of the far-end blade is smaller than that of the near-end blade. Compared with the prior art, the far-end blade and the far-end blade are arranged on the same cutter bar so that different types of machining can be conducted on the bushing hole, the cutter changing frequency of the cutter can be reduced, and the machining efficiency can be improved. Meanwhile, according to the compound cutter, the near-end blade and the far-end blade are detachably fixed to the cutter bar, so that the types of the blades can be replaced, the distance between the near-end blade and the far-end blade can be adjusted, and the same compound cutter can be suitable for machining bushing holes of different sizes; the flexibility and universality of the compound tool are improved.
