Abstract
The utility model discloses a composite drill bit with hard alloy material quality. The composite drill bit with the hard alloy material quality comprises a handle. A composite drill bit is in detachable connection with one end of the handle and sequentially comprises a first drill bit and a second drill bit from top to bottom. The first drill bit and the second drill bit are integrally formed. The composite drill bit with hard alloy material quality is novel in design, not easy to abrade and long in service life. A drill hole and a spot facing are accomplished machining in one time. Concentricity of the center of the drill hole and that of the spot facing are high, so that work efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of drill bit, relates in particular to a kind of carbide alloy material composite drill bit.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming.Drill bit commonly used mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.
After the general employing of common boring and spot-facing is holed first and finished, change wammel flower spot-facing again, use duration, efficient is low, and there are eccentric phenomena in spot-facing and the difficult assurance of boring concentricity, are unfavorable for assembling.Common brill flower material is poor, and attrition is large in frangibility, the boring, and efficient is low.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of carbide alloy material composite drill bit.
To achieve these goals, the technical solution adopted in the utility model is: a kind of carbide alloy material composite drill bit, comprise shank, one end of shank is removably connected with composite drill bit, composite drill bit comprises the first drill bit and the second drill bit from top to bottom successively, and the first drill bit and the second drill bit are one-body molded.
As preferably, the first drill bit is counterbit.
As preferably, the second drill bit is fluted drill.
Compared with prior art, the utility model has the advantage of: modern design, not easy to wear, long service life.Boring, spot-facing is disposable machines, and boring is high with spot-facing centres degree, so that operating efficiency is greatly high.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model;
Fig. 3 is example structure schematic diagram of the present utility model.
Among the figure: 1, shank; 2, the first drill bit; 3, the second drill bit; 41, boring; 42, spot-facing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of embodiment of the present utility model, consult Fig. 1, Fig. 2 and Fig. 3, the utility model comprises shank 1, and an end of shank 1 is removably connected with composite drill bit, composite drill bit comprises the first drill bit 2 and the second drill bit 3 from top to bottom successively, and the first drill bit 2 and the second drill bit 3 are one-body molded.The first drill bit 2 is counterbit.The second drill bit 3 is fluted drill.
The utility model is novel in design, and is not easy to wear, long service life.Boring 41, spot-facing 42 disposable machining, boring 41 is high with spot-facing 42 centres degree, so that operating efficiency is greatly high.
Although be recognized as a most practical and preferred embodiment and described the utility model in conjunction with current, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
