Description
Technical field
The utility model belongs to technical field of tools, more particularly to a kind of cable drill.
Background technology
In carpenter's auger processing, typically all carried out using drill bit.
And after the processing of wood products, typically cable is penetrated into wood products using penetration device, this mode its can be with
Realize the threading of cable.
But its operation of this mode is comparatively cumbersome and reduces production efficiency, poor practicability, it is also desirable to
Penetration device is purchased, cost is higher.
Secondly, existing this drill bit, its service life is shorter, larger mainly due to the cutting resistance bored when processing.
Utility model content
The purpose of this utility model be in view of the above-mentioned problems, provide one kind can increase the service life, cost can be reduced
More practical cable drill.
To reach above-mentioned purpose, the utility model employs following technical proposal：This cable drill includes drilling rod, in drilling rod
Lower end is provided with spiral cutting portion, and has helical flute in spiral cutting portion, and one layer of iron is provided with helical flute cell wall
Fluorine dragon wearing layer, the threading via hole through spiral cutting portion radial direction is provided with the middle part in spiral cutting portion, the two of threading via hole
End is respectively equipped with chamfering, and the circumferentially positioned plane of at least three and circle distribution is provided with the upper end sidepiece of drilling rod.
In above-mentioned cable drill, connected between adjacent two circumferentially positioned planes by arc convex surface.
In above-mentioned cable drill, described circumferentially positioned plane length is the 1/10 of run of steel.
In above-mentioned cable drill, described circumferentially positioned planar circumferential is uniformly distributed.
In above-mentioned cable drill, described Teflon wearing layer is Teflon wear-resistant coating.
In above-mentioned cable drill, described Teflon wearing layer thickness is less than 1mm.
In above-mentioned cable drill, described threading via hole is circular hole.
In above-mentioned cable drill, described run of steel is at least more than 3 times of spiral cutting minister's degree.
Compared with prior art, it is the advantages of this cable drill：
1st, set Teflon wearing layer, its can further increase the service life and further reduce Drilling operation when
Resistance, virtually extend service life.
2nd, the threading via hole set, it can be penetrated in order to what cable threaded, i.e. and it can further improve and penetrate efficiency,
Meanwhile structure is simpler and practicality is stronger.
3rd, it is simple in construction.
Brief description of the drawings
Fig. 1 is structural representation provided by the utility model.
Fig. 2 is the structural representation provided by the utility model for having wearing layer.
Fig. 3 is vertical view state structural representation provided by the utility model.
In figure, drilling rod 1, circumferentially positioned plane 11, arc convex surface 12, spiral cutting portion 2, helical flute 21, threading are logical
Hole 22, chamfering 23, Teflon wearing layer 3.
Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As Figure 1-3, this cable drill includes drilling rod 1, and spiral cutting portion 2, and spiral cutting are provided with the lower end of drilling rod 1
There is helical flute 21, the length of drilling rod 1 is at least more than 3 times of the length of spiral cutting portion 2 in portion 2.
Drilling rod 1 is made up of metal material.
The front end in spiral cutting portion 2 is provided with wedge angle.
One layer of Teflon wearing layer 3 is provided with the cell wall of helical flute 21, the Teflon wearing layer 3 is that Teflon is wear-resisting
Coating.
The Teflon wearing layer 3 of setting, the thickness of Teflon wearing layer 3 are less than 1mm.It can further extend using the longevity
Resistance when life and further reduction Drilling operation, virtually extends service life.
The threading via hole 22 through the radial direction of spiral cutting portion 2 is provided with the middle part in spiral cutting portion 2, threading via hole 22 is circle
Hole.Chamfering 23 is respectively equipped with the both ends of threading via hole 22, chamfering 23 is circular arc chamfering or ramp down angle.
The threading via hole 22 of setting, it can be penetrated in order to what cable threaded, i.e. and it can further improve and penetrate efficiency,
Meanwhile structure is simpler and practicality is stronger.
The circumferentially positioned plane 11 of at least three and circle distribution is provided with the upper end sidepiece of drilling rod 1.Two adjacent week
Connected between positioning plane 11 by arc convex surface 12.
The circumferentially positioned length of plane 11 is the 1/10 of the length of drilling rod 1.
The circumferentially positioned even circumferential of plane 11 distribution.
By setting circumferentially positioned plane 11, it may insure the circumferential stability of clamping.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
