Abstract: The quantitative relation between parameters and performance of the impregnated diamond bit has always been a weak research area in the study of the diamond bit. In this paper, the quantitative analysis, rigorous theoretical calculation and derivation are both employed to obtain the quantitative relation between the diamond bit efficiency and life span and the diamond bit parameters. The conclusion from the quantitative research is in perfect conformity with the qualitative results concerned, indicating that the research is feasible into the quantitative relation between the diamond bit performance and the diamond bit parameters. The result of the quantitative relation between the diamond bit performance and the diamond bit parameters can be applied to the guidance to the diamond bit parameter design that might be used to forecast the performance of the diamond bit.
