PDC drill bit with super long life, high efficiency and wide application.
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.
PDC drill bits (non-core bits)
Application for penetration of gas hole, water-discharging hole, and grout hole under coal mine.
PDC Drill bits (core bits)
Application for core drill of coal system stratum with hardness coefficient f<10 in geological exploratory.
