Bionics was applied in the design of the impregnated diamond bit． Based on previous research and the 63# bit matrix formula，a new non-smooth bionic impregnated diamond bit with a single circular ring was designed and manufactured，and also tested indoor． The results were satisfactory． During its shape contacted surface system，non-smooth shape display some structure merits such as decreasing resistance． It was obvious that the drilling efficiency of the bionics bit is much higher than that of ordinary's one，and so does the working life of bionic bit．
