For the manufacturing and forming of the taper shank twist drill, the hot rolling and twisting process is generally used in China. The taper length drill bit is characterized by the step-by-step forming sector plate hot-rolled into straight grooves, then twisted into spiral grooves, and then processed to standard requirements. The advantages of the Taper Shank Drill Bit process are high production efficiency, full use of raw materials, and the internal structure of the processed drill bit body has fiber continuity, fine grains, uniform carbide distribution, and high red hardness.
The main process flow of Shank Drill Bit rolling and twisting: blanking → shank → blank processing → rolling groove → twist groove → turning processing → heat treatment → finishing
