Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment: as shown in Figure 1-2, this utility model provides one to open rock drill bit, including drill body 1, drill body 1
Side is provided with the first Cylindrical Blade 8, and the first Cylindrical Blade 8 side is provided with the first helical blade 2；First helical blade 2
Side is provided with the first rhombus blade 3, and the first rhombus blade 3 side is provided with the second Cylindrical Blade 10；Second Cylindrical Blade
