Therefore, it is necessary to provide an innovative and progressive drill bit to solve the above problems.

The main purpose of this creation is to improve the problems caused by the defects in the design of the drill bit for the dental bone drilling work, and to provide a drill bit structure, in addition to drilling the tooth bone, and controlling the drill bit tail drilling In addition to the depth, it can also help confirm the exact position of the drill hole, which is helpful for the installation and stability of the implant.

According to the bone drill structure provided by the present invention, the drill body comprises a drill body, a nut and an adjusting ring. The bit body is a thin rod body, and the upper end forms a joint portion for connecting the driving end of the dental handpiece and rotating it at a high speed, and the bottom end forms a drilling portion, which has the ability of cutting drilling; in particular, above the drilling portion a threaded section is provided; the nut is a hex nut that can be screwed to the threaded section of the drill body, and the adjusting ring has a predetermined loop width, and a hexagonal nut pit is recessed in the center for the nut The anastomosis is placed, and a screw hole is arranged in the center of the adjusting ring, which can be screwed to the aforementioned thread segment. Thereby, the purpose of controlling the drilling depth of the drill bit and confirming the drilling position can be achieved. .
