PDC drill bits:

New products with super long life, high efficiency and wide application.

1. Super long life-as *0 times as cemented carbide drill bits under the same condition.
2. High efficiency-Times of lifting the drilling machine could be reduced sharply, and the average time efficiency could be increased more than 2 times.
3. Wide range of application-it could have a penetration of rock formation with f ≤*2,especially for the rock formation with f=***0.
