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.

1. PDC drill bits (non-core bits)

  Application for penetration of gas hole, water-discharging hole, and grout hole under coal mine.

  Size: dia 48-dia 270mm

  Concave model,  Pillar model, Blade model, Expansion model

2. PDC Drill bits (core bits)

  Application for core drill of coal system stratum with hardness coefficient f<10 in geological exploratory.  Size: dia 56- dia 133mm
