The utility model can be embodied in many different forms of embodiments, and the protection scope of the utility model is not limited to the embodiments mentioned in the text.

The size and thickness of each component shown in the drawings are arbitrarily shown, and the utility model does not limit the size and thickness of each component.

The outer diameter of the second blade 42 is not greater than the inner diameter of the first blade 41 .

[0045] The first cutting edge 41 includes a first tapered cutting edge and a second tapered cutting edge intersecting in sequence, the second tapered cutting edge is arranged on the rear side of the first tapered cutting edge, the angle between the first tapered cutting edge and the longitudinal axis L of the tool body 3 is 27°, and the angle between the second tapered cutting edge and the longitudinal axis L of the tool body 3 is 75°.
