Abstract

The invention provides a chamfering drill bit which comprises a drill bit tip, a drill bit, a chamfer angle and a chamfering machine. The drill bit tip and the drill bit are integrally manufactured, both the diameter and the radius of the drill bit are smaller than both the diameter and the radius of the chamfering machine, the chamfer angle is connected onto the drill bit, the chamfer angle and the drill bit are integrally manufactured, the chamfering machine and the chamfer angle are integrally manufactured, and the chamfering machine is connected to the upper end of the chamfer angle. The chamfering drill bit has the advantages that the chamfering drill bit is widely applicable to machining brittle and hard nonmetal materials, can complete drilling and chamfering at one step, and is high in drilling efficiency, and the problem of gap bands in the prior art is solved.

Description

A kind of chmfer bit
Technical field
The present invention relates to a kind of drill bit, particularly a kind of chmfer bit.
Background technology
In the prior art, crisp hard nonmetallic materials are finished boring and chamfering, generally be by boring after again operation of chamfering finish, when using the method for the chamfering of holing earlier again, must change different instrument and contraposition through secondary, often cause off-centre because the center contraposition is inaccurate, general rice is said, must just can carry out with accurate correction and test through skilled skilled worker earlier, this method is not only wasted test article, and more the increase because of operation influences work efficiency.
Summary of the invention
In order to solve the problem that tradition exists, to the invention provides following technical scheme be:
A kind of chmfer bit, described chmfer bit, comprise drill bit, drill bit, chamfering, chamfering body, described drill bit and drill bit are made one, described bit diameter and radius are all less than the chamfering body, described chamfering is connected on the drill bit and makes one with it, and described chamfering body and chamfering are made one and be connected its position, upper end.
Further, described drill bit is 90 degree.
The beneficial effect that the present invention brings is:
The present invention is by arranging chamfering and be connected on the drill bit and make with it one, chamfering body and chamfering are set to be made one and is connected its position, upper end, can be widely used in the processing of crisp hard nonmetallic materials, can disposablely finish boring and chamfering, the drilling efficiency height, solve the problem of prior art intermediate gap band.
 
Description of drawings
Fig. 1 is structural representation of the present invention.
Number in the figure is:
1-drill bit, 2-drill bit, 3-chamfering, 4-chamfering body.
The specific embodiment
Below to by reference to the accompanying drawings preferred embodiment of the present invention being elaborated, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
As shown in Figure 1, a kind of chmfer bit, described chmfer bit, comprise drill bit 1, drill bit 2, chamfering 3, chamfering body 4, described drill bit 1 is made one with drill bit 2, and described drill bit 2 diameters and radius are all less than chamfering body 4, and described chamfering 3 is connected and makes one on the drill bit 2 and with it, described chamfering body 4 is made one with chamfering 3 and is connected its position, upper end, and described drill bit 1 is 90 degree.
In sum, the present invention is by arranging chamfering and be connected on the drill bit and make with it one, chamfering body and chamfering are set make one and be connected its position, upper end, described chmfer bit can be widely used in the processing of crisp hard nonmetallic materials, can disposablely finish boring and chamfering, have the high advantage of drilling efficiency, solved the problem of prior art intermediate gap band, increased output, improved workman's operating efficiency, and the operation degree of accuracy.
The above; it only is one of the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.

Claims (2)
