This invention discloses a roughing and finishing integrated turning insert, belonging to the technical field of metal cutting tools, comprising a cutting section and sidewalls. The cutting section forms multiple cutting zones, including a sequentially connected tip area, a first cutting zone, a second cutting zone, and a third cutting zone. By dividing the cutting section into multiple cutting zones, the insert forms a spatially varying structure with progressively decreasing sharpness and structural strength.
