Abstract
The invention discloses a multifunctional spiral bit which comprises a bit handle, a limiting device, a spiral drill body and a locating tip portion. The bit handle is arranged at the right end, and the limiting device is arranged on the left side of the bit handle. The spiral drill body is arranged on the left side of the limiting device, and composed of spiral grooves, a bit wing and spiral ridges. Each spiral groove is formed by every two adjacent spiral ridges. The diameter of the right half portion of the spiral drill body ranges from 10 mm to 12 mm, and the diameter of the left half portion of the spiral drill body ranges from 8 mm to 10 mm. The locating tip portion is arranged at the end of the left side of the spiral drill body. According to the multifunctional spiral bit, the problem that holes with different diameters on the same straight line cannot be drilled through the same bit can be solved, meanwhile, the problem that the drilling discharge efficiency of a bit in the work process is not high is solved well, and the problem that the bit is likely to carry out excessive drilling is further solved.
Description
technical field [0001] The invention belongs to the technical field of drilling, and in particular relates to a multifunctional helical drill bit. Background technique [0002] In the aluminum profile door and window processing industry, drilling operations are very common, and the processing frequency of drilling operations is also high; especially when processing the fixing holes of the door and window frames, when the profile section is a double-layer or multi-layer cavity structure At the same time, it is necessary to drill holes of different diameters in the inner layer and the outer layer at the same position of the profile, and ensure that the two holes are concentric. If adopt the drill bit of different diameters respectively in this case, outer layer drilling operation, just can't guarantee that two holes are concentric, influence the fixed installation of on-site door and window frame. In addition, the auger bit in the prior art has the bad situation of drilling c...
