Artificial diamond drill bit and manufacturing method thereof

The invention discloses an artificial diamond drill bit and a manufacturing method thereof.The artificial diamond drill bit is manufactured through the steps of blank body machining, drill bit turning, polishing and polishing, thread machining, drill bit electroplating and the like, the artificial diamond drill bit comprises a drill body, a plurality of tooth roots are arranged at the bottom of the drill body in an annular array mode, and a plurality of drill teeth are arranged on each tooth root at equal intervals; according to the diamond drill bit, the drill teeth on the tooth roots are in an arc shape, the radiuses of the arc-shaped drill teeth are different, when the diamond drill bit rotates, the rotating path of each drill tooth is in a round shape, the paths of all the drill teeth rotating at the same time just form a round face, a better drilling effect is achieved, and when a hard object is drilled, the drill teeth are not prone to falling off. According to the drilling tool, drilling paths can be b
