Embodiment Construction

[0010] Such as figure 1 , figure 2 and image 3 As shown, a drill bit of the present invention includes a drill shank 1, and the drill shank 1 includes a section of hexagonal cylinder 1c, see image 3 As shown, the hexagonal cylinder 1c is provided with an annular positioning groove 1b, see figure 2 As shown, the drill shank 1 is also provided with an axial positioning groove 1a. The hexagonal cylindrical drill shank 1 is more suitable for the traditional drill chuck. The hexagonal cylindrical drill shank 1 with a ring-shaped positioning groove 1b is suitable for clamping by a hexagonal converter. , to lock the bit. The drill shank 1 is provided with an axial positioning groove 1a to accommodate different types of converter clamping.

[0011] The above-mentioned examples are only to illustrate the present invention, but not to limit the present invention. The present invention can also be implemented in other ways, which will not be repeated here. Any technical solut...
