| Abstract: | A new type of impregnated diamond bit with two sorts of diamond abrasives has been developed, which can improve both penetration rate and service life simultaneously. Field drilling experiments have verified the advantages of the new bits, and the all round performance index of the new bits increased 179% compared with that of the traditional bits. |
