Further, described drill body body front end also includes two groove for cuttings, described groove for cuttings extends to bottom from the start-up portion of drill body body leading section in a helical pattern, on arbitrary cross section of drill body body, groove for cuttings is all located at position diametrically opposed to each other in drill body plane, and drill body body front end is divided into four parts by said two groove for cuttings uniformly.
Further, described positioning groove is the groove offering four semicircle strips along cylinder drillstock periphery.
The beneficial effects of the utility model are as follows:
1, main cutting cutter, S-shaped pair cutting edge, these three cuttves of circumference cutting edge and chip discharging structure are effectively combined by drill bit of the present utility model, it is achieved three grades of borings, once-forming, and chip removal is unobstructed, it is achieved the smooth of cutting face of holing；
2, apex point of the present utility model, drill body body front end, the setting of ratio of maximum gauge of drill body body rear end, beneficially the stablizing of structure in boring procedure, is difficult to phenomenon fracture occur；
3, the leading section of drill body body of the present utility model uses obform body, and the rearward end of drill body body is cylinder, and obform body combines with cylinder, can realize three grades of borings, once-forming, the smooth of cutting face of holing, and can guarantee that again the stablizing of structure of drill body body；
4, drill bit of the present utility model is provided with two groove for cuttings on drill body, said two groove for cuttings extends to bottom from front end in a helical pattern, along arbitrary cross section of drill body, groove for cuttings is all located at position diametrically opposed to each other, the groove for cuttings of this symmetric figure in drill body plane, and row's bevel is long-pending big, it is fast that row cuts speed, does not easily cause the broken accumulation cut；
5, there are the groove of 4 the semicircle strips offered along cylinder drillstock periphery, the design of such groove to serve the effect of fastening, Embedded drillstock outside drillstock of the present utility model, can effectively prevent drill bit from installing landing machine；
6, drill bit of the present utility model uses surface to have the conical structure of helical structure, so during drilling through hole, reduces stress surface, increases the automatic entrance-exit in borehole strength, beneficially working angles, and stock-removing efficiency will be greatly improved；
7, apex point of the present utility model uses two main cutting cuttves, and two circumference cutting edges and two secondary cutting edges are worked in coordination, and accelerate cutting speed, it is ensured that the fineness in cutting face.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
If Fig. 2 is left view of the present utility model shown in Fig. 1.
Detailed description of the invention
Drawing reference numeral: 1, apex point, 2, main cutting cutter, 3, circumference cutting edge, 4, groove for cuttings, 5, secondary cutting edge, 6, drillstock, 7, positioning groove, 8, drill body body, 9, drill body body leading section 10, embodiment of the present utility model, for making utility model purpose of the present utility model, technical scheme and advantage clearer, is described in further detail by cylinder drill body rearward end below in conjunction with accompanying drawing.
The structure of timber Special drill drill bit of the present utility model is as shown in Figure 1, a kind of timber Special drill drill bit, connected and composed by drillstock 6, drill body two parts, the structure of drill body is made up of apex point 1 and drill body body 8 two parts monolithic molding, and drill body body 8 is made up of drill body body leading section 9 and cylinder drill body rearward end 10 monolithic molding on the same axis of the ∞ font body that two ends are straight end face；Be provided with horizontally disposed S-shaped pair cutting edge on drill body body leading section 9 along ∞ font position, S-shaped pair cutting edge 5 and drill body body 8 are monolithic molding, and S-shaped pair cutting edge 5 and described drill body body 8 level angle are 30～45 °；Drill body body leading section 9 also includes two groove for cuttings 4, described groove for cuttings 4 extends to bottom from the start-up portion of drill body body leading section 9 in a helical pattern, on arbitrary cross section of drill body body 8, groove for cuttings 4 is all located at position diametrically opposed to each other in drill body plane, the groove for cuttings of this symmetric figure, row's bevel is long-pending big, and it is fast that row cuts speed, does not easily cause the broken accumulation cut.The structure of drillstock 6 is slender cylinder structure, one end at drillstock 6, near end position, it is provided with positioning groove 7,4 the semicircle strip grooves offered along cylinder drillstock periphery outside drillstock 6, the design of such groove serves the effect of fastening, Embedded drillstock, can effectively prevent drill bit from installing landing machine.Circumference cutting edge 3 is positioned at secondary cutting edge 5 front end, and these three cuttves of main cutting cutter 2, S-shaped pair cutting edge 5, circumference cutting edge 3 and chip discharging structure effectively combine, it is achieved three grades of borings, once-forming, and chip removal is unobstructed, it is achieved the smooth of cutting face of holing.
