1. PDC Drill Bits
Various Products
PDC drill bits:
New products with super long life, high efficiency and wide application.
1) Super long life-as 10 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 ≤12,especially for the rock formation with f=5-10.
