The life of the bit is not only affected by the rock it acts on, but also depends on its own properties, structure, and other performance parameters. Because the nature and composition of the rock are uncontrollable factors, the quality of the bit itself can be improved through reasonable design and advanced manufacturing processes. For the diamond bit itself, among the factors affecting its life, the wear resistance of the bit plays a decisive role (under some conditions, the wear resistance of the tire body is consistent with the hardness and erosion resistance of the tire body. For example, in the case of the same tire body formula, the higher the wear resistance and erosion resistance of the tire body is, the higher the wear resistance and erosion resistance of the tire body is). The wear resistance of the bit includes the wear resistance of lip diamond and the wear of body material. In a diamond-impregnated bit, these two aspects should cooperate with each other to achieve good results, that is, the wear of diamond is slightly slower than that of the tire body, so as to ensure the continuous cutting of diamond in the drilling process, maintain the high efficiency of the bit, and improve the efficiency of drilling construction. Otherwise, it will cause the bit to not out of the edge and fail.
