1) Super long life-10 times than cemented carbide drill bits under the same condition.
2) High efficiency-Time of lifting the drilling machine could be reduced sharply, and the average time effciency could be increased more than 2 times
3) Wide range of application-it could have a penetration of rock formation with f≤ 12, especially for the rock formation with f=5-10.
