[0002] In dental surgery, dental implant drill bits are relatively common tools, which are mainly used to prepare implant holes in the alveolar bone of patients. The existing dental implant drill bits have low drilling efficiency, cannot discharge the cut bone chips in time, and a large amount of heat will be generated due to the friction between the drill bit and the teeth during the drilling process. At this time, it is necessary to dissipate heat from the drill bit. The drill bit needs to be cooled multiple times during a dental surgery, resulting in a significant increase in the time of dental surgery, low efficiency, and excessive resource consumption.

The notches 15 penetrate both sides of the second cutting edge 14 to communicate adjacent chip discharge grooves 16. A plurality of the notches 15 are distributed spirally along the drill bit body 10. The spiral distribution facilitates the drill bit to carry out bone chips during rotation. At the same time, the notches 15 can evenly divide the bone chips into each chip discharge groove 16 to avoid blockage. By providing the first cutting edge 11 at the free end of the drill bit, the second cutting edge 14 on the outer side wall of the drill bit body 10, and at the same time providing the chip discharge groove 16 and the notches 15 to timely discharge the cut bone chips, the cutting efficiency is greatly improved, and the problems of long dental surgery time and excessive resource occupation are solved.

[0023] The first cutting edge 11 has a step surface 12 and a cutting edge surface 13. The inner side of the step surface 12 is connected to the lower side of the cutting edge surface 13. The step surface 12 is inclined from the inside to the outside along the center of the drill bit body 10. By providing the step surface, the first cutting edge 11 can quickly drill a hole and discharge the bone chips to the chip discharge groove 16.

[0024] The pitch of the second cutting edge 14 extending spirally along the body is 1.3 cm.

[0025] The number of the second cutting edges 14 is four; the four second cutting edges 14 are evenly distributed on the outer side of the drill bit body 10.

[0026] It should be understood that the number of the second cutting edges 14 can be set according to actual use needs.

[0027] The distance between multiple of the said notches located on the same second cutting edge is 2.5 cm. By setting an appropriate distance, the notch 15 can evenly distribute bone chips to each chip removal groove 16, improving the chip removal efficiency.

[0028] Both the drill bit body 10 and the clamping shank 20 are solid structures.

[0029] The drill bit body 10 and the clamping shank 20 are integrally formed, and a clamping section 21 is provided at one end of the clamping shank 20 away from the drill bit body 10.

[0030] The usage method of the present utility model: Clamp the clamping section 21 of the clamping shank 20 with a drilling machine, and then align the first cutting edge to abut against the position where drilling is required to perform drilling.

[0031] In summary, the present utility model sets a first cutting edge 11 at the free end of the drill bit, a second cutting edge 14 on the outer side wall of the drill bit body 10, and at the same time sets a chip removal groove 16 and a notch 15 to timely discharge the cut bone chips, realizing a greatly improved drilling efficiency of the drill bit, thereby avoiding the need for multiple heat dissipations of the drill bit, reducing the time of dental surgery, and improving the resource utilization rate.
