The bionics theory was applied on the spiral bits,and then a non-smooth spiral bit was designed and processed for carried out the problem of serious sticking.Experiments finally proved that the bionic non-smooth spiral bit has a significant effect in the area of desorption and reducing resistance,compared with the conventional spiral bit,the desorption rate and drilling efficiency have been enhanced 70% and the fuel consumption has been decreased 53.3%.So it is novel tool for drilling of large diameter spiral.
