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.
