The invention mainly solves the technical problem of providing a kind of small-sized Two head drill bit, double end work does not account for placement space,
Cutter utilization rate is high.
In order to solve the above technical problems, one aspect of the present invention is：A kind of small-sized Two head drill bit is provided, is wrapped
It includes：Drill body, drill bit and drill bushing, the drill bushing and the mating setting of drill body, the drill body are provided at both ends with drill bit,
The bit face is provided with brill silk, and the drill bit is cone, and the drill body is made into integration with drill bit, before the drill bit
Side is provided with the multiple polishings nail being made into integration, and the polishing nail is cylindrical-shaped structure, and polishing nail surface is coated with anti-corrosion painting
Expect, fixed card buckle is provided in the drill bushing.
In a preferred embodiment of the present invention, the drill body and drill bit are hard aluminium alloy material.
In a preferred embodiment of the present invention, the entire length of the small-sized Two head drill bit is 30-35mm.
In a preferred embodiment of the present invention, the length ratio of the drill body and drill bit is 0.8：1.1.
In a preferred embodiment of the present invention, each bit face is provided with 6 polishing nails.
In a preferred embodiment of the present invention, the apex angle of each drill bit is 35 degree.
The beneficial effects of the invention are as follows：A kind of small-sized Two head drill bit that the present invention points out, double end work, it is empty not account for placement
Between, cutter utilization rate is high, and the polishing nail of bit face is effectively increased drilling dynamics and perforated area.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein：
Fig. 1 is a kind of structural schematic diagram of one preferred embodiment of small-sized Two head drill bit of the present invention.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of small-sized Two head drill bit, including：Drill body 1, drill bit 2 and drill bushing 3, the drill bushing 3 is matched with drill body 1 to be arranged
It sets, the drill body 1 is provided at both ends with drill bit 2, and 2 surface of the drill bit, which is provided with, bores silk 4, and the drill bit 2 is cone, institute
It states drill body 1 to be made into integration with drill bit 2,2 front side of the drill bit is provided with the multiple polishings nail 5 being made into integration, the polishing
Nail 5 is cylindrical-shaped structure, and the polishing follows closely 5 surfaces and is coated with anticorrosive paint, and fixed card buckle is provided in the drill bushing 3.
The drill body 1 and drill bit 2 are hard aluminium alloy material, and intensity is high, not easy to wear, effectively improves using the longevity
Life.
The length ratio of the drill body 1 and drill bit 2 is 0.8：1.1, it is reasonable for structure, it is steady when increasing bit operation
It is qualitative.
2 surface of each drill bit is provided with 6 polishing nails 5, and by polishing, nail 5 is polished, and is effectively increased drilling power
Degree and perforated area.
In conclusion a kind of small-sized Two head drill bit that the present invention points out, double end work, do not account for placement space, cutter uses
Rate is high, and the polishing nail of bit face is effectively increased drilling dynamics and perforated area.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
