In the present embodiment, the first projection 71 and the second projection 72 are each symmetrical with respect to the bisector of the circular arc cutting edge 51. Thus, the generated chips can be brought into good contact with the side surface 712 of the first land 71 and the side surface 722 of the second land 72 along the bisector of the circular arc cutting edge 51 at the small cutting depth, and the chips can be discharged stably.
With this configuration, the distance to be applied to the chips increases with the increase in the cutting depth, and the curl diameter of the chips can be adjusted, thereby stably curling the chips. In a word, under the action of the structure, the excellent chip removal and breaking capacity can be displayed under wide working conditions.
In the present embodiment, as shown in fig. 6, the rake surface 61 and the small portion rake surface 62 are provided between the circular arc cutting edge 51 and the first protrusion 71, and the rake surface 62 is provided between the line segment cutting edge 52 and the first protrusion 71 or the second protrusion 72.

This ensures the sharpness of the line segment cutting edge 52.
With this configuration, in a small cutting depth, the generated chips can be curled by the rake surface 61 of the first protrusion 71 first, and then stably curled by the side surface 712 of the first protrusion 71, so that the chips can be smoothly discharged.

This structure can prevent the tool from unnecessarily contacting the machined surface of the workpiece.

According to the invention, the specific protruding structures (namely the first protrusion 71 and the second protrusion 72) are designed in the chip grooves, so that the sufficient chip containing space is ensured, the sharpness of the tool is enhanced, the effect of the chip containing space on the chip is enhanced, the chip can be effectively controlled during small-feed small-cut-depth machining and cutting-depth change of small parts, and the service life of the tool and the surface quality of a workpiece are improved. The invention can effectively reduce the blockage of the chips at the positions of the rake face 6 and the bulge 7 by the chip processing function of the side face 722 of the second bulge 72 under the working condition of small cutting depth and large feeding. In the case of small-depth cutting, the generated chips are effectively processed at the first side surface 712 of the circular truncated cone-shaped protrusion 71 by the rake surface 6. As the cutting depth increases, the main location of chip disposal is gradually shifted from the side 712 of the first protrusion 71 to the side 722 of the second protrusion 72. Like this, in certain depth of cut within range, no matter be little depth of cut or big depth of cut, or the operating mode processing that changes at the depth of cut, can both properly effectively handle the smear metal for the smear metal can be stabilized curly, and the fracture is smoothly discharged.
