Abstract
The invention discloses a telescopic iron chip processing drill bit which comprises a drill bit body and an attraction device connected with the drill bit body. The drill bit body is movably arranged at one end of the attraction device and comprises a drill point and a drill body. The drill point is formed by combination of triangular pyramids which are shaped like a Chinese character 'shan'. Drill body cutting threads are evenly arranged on the drill body. A first chip discharge slot is formed between every two cutting threads. The attraction device is of a hollow structure. A transmission device is arranged on the inner side of the attraction device and provided with a limiting device. The drill body and the transmission device are movably connected. A spiral coil is arranged inside the attraction device and connected with a power source. A second chip discharge slot and an iron chip collection slot are formed in the outer side of the attraction device. The drill bit can attract drilling iron chips in the drilling process, so that the follow-up procedure of removing iron chips is omitted, and manpower and material resources are saved; besides, the length of the drill bit can be adjusted.
