1. Features of hole opener bits
Hole Openers are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. A Hole Opener is sometimes referred to as a Reamer.
2. Advantages of hole opener bits
Directional crossing operation is widely used in unexcavated project. Three steps in such operation are: 1, oriented hole operation; 2, hole opening; 3, pipe pulling. Hole opening is the most onerous task in this operation, but, the key for hole opening operation is the hole opener choosing according to the operation equipment and formation.
3. Cutting Structure
Combined by single TCI cone bit, IADC 537.
4. Seal and Lubrication
High performance HNBR O-ring for bearing seal and advanced grease for lubrication.
5. Product Application
It is suitable for the large size well, HDD, trenchless and infrastructure applications.
