Description
Technical field
The utility model belongs to the carpenter field, more particularly, relates to a kind of carpenters auger.
Background technology
The instrument that is applicable to drilling timber in prior art is mainly two kinds of common fluted drill and flat-wing drillers, and the hole got out in actual use is bright and clean not, and, because the resistance of cutting is large, is difficult to automatic propelling, and penetration rate is effort slowly and very.Therefore, how addressing the above problem, is problem demanding prompt solution.
The utility model content
The purpose of this utility model is to provide the fast carpenters auger of a kind of penetration rate.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: a kind of carpenters auger comprises the taper spiral shell point, cutter hub and the drillstock that connect as one successively, wherein, be provided with spiral grooves, main cutting edge and front cutting edge on cutter hub, on taper spiral shell point, be provided with spiral salient.
Above-mentioned a kind of carpenters auger, described drillstock is hexagonal prism.
The utility model adopts above-mentioned structure, by be provided with spiral grooves, main cutting edge and front cutting edge on cutter hub, on taper spiral shell point, is provided with spiral salient, can better advance, and penetration rate is fast, has increased operating efficiency.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model.
In figure: 1 is taper spiral shell point, and 2 is cutter hub, and 3 is drillstock, and 4 is spiral grooves, and 5 is the main cutting cutter, and 6 is secondary bite, and 11 is spiral salient.
The specific embodiment
As shown in Figure 1, a kind of carpenters auger, comprise the taper spiral shell point 1, cutter hub 2 and the drillstock 3 that connect as one successively, is provided with spiral grooves 4, main cutting edge 5 and front cutting edge 6 on cutter hub 2, on taper spiral shell point 1, is provided with spiral salient 11.
The utility model is when specifically being used, and when boring, the spiral salient 11 be arranged on taper spiral shell point 1 can make boring can not need other propulsive force just can lean on self revolving force automatic entrance-exit, and penetration rate is fast, has increased operating efficiency.
