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.
Specification:
Take our 8 1/2 JTW1462 PDC bit as an example
