Abstract:
This invention provides a corrosion-resistant and wear-resistant geological drill bit and its manufacturing method, related to the home kitchen field. The drill bit includes a drill rod with an internal cavity, in the middle of which is fixedly connected a positioning plate. One side of the positioning plate is fixedly connected to a positioning sleeve, inside of which is fixedly connected the first cooling tube. Below the positioning plate and fixedly connected to it is the second cooling tube. The lower end of the drill rod is fixedly connected to a drill seat, whose outer surface is fixedly connected with cutting slices, and the lower end of the drill seat is fixedly connected with wear-resistant blocks, the lower surface of which is fixedly connected with wear-resistant heads. Through the first and second cooling tubes, the temperature of the drill bit is reduced during drilling, extending the life of the drill bit.
