Specifications

TCI tricone bit
1.high toughness
2.high durability
vers almost all IADC code

PDC (Polycrystalline Diamond Compact) is composed of diamond micron powder and cemented carbide liner than are sintered toghether under high temperature and high pressure. It not only has the high wear resistance that diamond has, but also has the high impact-resistance toghness.

 

 

Compared with the steel body bits, the matrix body is more suitable for hard rock. And the bits lifetime is two times than the steel body. We can provide the size from 3¹/₂ inch to 12¹/2 inch. 

 

Characteristics:

• Using special cutting structure, making the bit works stably. It could be maintained higher drilling speed during the bit rotaries drilling;
• Using high performance compound piece combination , enhances the bit life;
• The highly polished cutter could be reduce the frictional resistance and quicken discharge fragment, so that improve the cutting efficiency;
• Unique design with different stability makes the bit in stability state when drilling;
• Deep-wide junk slot could carry fragment against the oil well that is better for bit cleaning and cooling;
• Suitable for drilling soft to medium-hard formation, such as mudstone, sandstone, limestone etc.;
• We could supply the quantity of the bit blade from 3 to 12 pcs as per your needs;
• We could make the bit as per your specific needs/ drawing/ sample.
