Abstract
The utility model relates to a woodworking twist drill which comprises a polygon-prism-shaped drillstock and an auger bit. The woodworking twist drill is characterized in that the polygon-prism-shaped drillstock and the auger bit are integrated. The woodworking twist drill has the advantage of being of an integral structure and the like.
Description
Technical field
The utility model is specifically related to a kind of twist drill for wood working, belongs to the cutting tool technical field.
Background technology
Existing twist drill for wood working all is to be cooperated by hexagon prism drillstock and the spiral bit axis hole by between the two, and by the binding agent bonding fixedly connected (as shown in Figure 4).There is certain shortcoming in the twist drill for wood working of this split interconnection system structure, because the hexagon prism drillstock is connected between the mating surface with the spiral bit axis hole and can has certain interval, when this just unavoidably can cause spiral bit to produce circular runout under operating mode, so that directly influence its drilling accuracy of boring, also can cause drillstock to separate with drill bit in the time of seriously and influence ordinary production.
Summary of the invention
The purpose of this utility model is to provide a kind of twist drill for wood working of integral structure, to overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model is: a kind of twist drill for wood working, comprise polygon prism drillstock and spiral bit, and its: described polygon prism drillstock and spiral bit be one each other.
In technique scheme, described polygon prism drillstock is the six prismatic drillstocks that are regular hexagon, or is just dimetric quadrangular drillstock.
In technique scheme, be provided with the round bottom annular groove at close its free end position of described polygon prism drillstock, and described round bottom annular groove is equipped mutually with the radial screw of carpenter chuck.
The good effect that the utility model has is: owing to adopted the twist drill for wood working of said structure, its polygon prism drillstock and spiral bit be one each other, can not cause spiral bit under operating mode yet, because drillstock hole and drill bit connect the gap between the face, and when producing circular runout, also can occur rocking and throwing off, and unsettled phenomenon, make the twist drill for wood working of this integral structure bore the drilling accuracy height, realized the purpose of this utility model.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the structural representation of the twist drill for wood working of prior art.
The specific embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is further described, but is not limited thereto.
As shown in Figure 1, 2, 3, a kind of twist drill for wood working comprises polygon prism drillstock 1 and spiral bit 2, and its: both one each other of described polygon prism drillstock 1 and spiral bit 2.Twist drill for wood working of the present utility model is steelwork.
Described polygon prism drillstock 1 is the six prismatic drillstocks that are regular hexagon, or is just dimetric quadrangular drillstock.
The utility model is provided with round bottom annular groove 1-1 described polygon prism drillstock 1 near its free end position, and described round bottom annular groove 1-1 is equipped mutually with the radial screw of carpenter dog.
The utility model lab scale effect shows, is very gratifying.
