Abstract
Disclosed is an anchor rod drill bit. The drill bit comprises a drill stock portion and a drill bit base portion, wherein the drill stock portion and the drill bit base portion are integrally formed, a drill edge blade is arranged on the drill bit base portion, the drill bit base portion comprises at least two wing bodies which are spirally arranged around an axle center, the drill edge blade is installed at the upper ends of the wing bodies, a chip discharging slot is arranged at the connection position of the lower portions of the wing bodies and the drill stock portion, and a diagonal plane which penetrates through the chip discharging slot is arranged on the upper portion of the drill stock portion. A water passage is arranged in the drill bit, the water passage is communicated to the center of the drill bit base portion and penetrates through the center of the drill bit base portion through a rectangular flat hole, and connecting threads are arranged in the water passage. The anchor rod drill bit is in an integral structure, the installation is simplified, and the connecting strength of a drill rod and the drill bit is improved. Furthermore, the rectangular flat hole serves as a water outlet, water outlet strength is large, impulsive force is strong, clips are discharged conveniently, and the failure rate is reduced.
