[0031] Further, as a preferred embodiment of this solution rather than a limitation, the tool shank 1 is cylindrical, which is convenient for machine tool clamping and prevents offset and dislocation during processing.

[0032] Further, as a preferred embodiment of this solution rather than a limitation, the milling and forming portion 2 includes a first milling portion 21 near the tool shank 1 for milling the first part of the outer edge of the golf club head.
