PDC drill bits:

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

1) Super long life-10 times than 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 12,especially for the rock formation with f=5-10.
