1. Hole Opener
1. Begin your drilling journey by first creating a smaller hole and effortlessly expanding it with our state-of-the-art hole opener. This method epitomizes conventional drilling technology, particularly when the drilling machinery has limited power or when the final hole size is exceptionally large.
of regular drilling technology when the drilling machine is lower power or the end-hole is too big.
2. Tailored specifically for your needs, we offer customizable hole openers and solutions based on rock hardness, desired drilling depth,
size of the pilot hole, size of the end-hole.
3. When tricone bits are used as pilot bits, the hole opener transforms into a rock bit. This configuration employing tricone bits is highly effective for well drilling requiring special sizes.
as pilot bits is always applicable in special sizes well drilling.
4. The reamer is predominantly constructed with four or more robust cones.
5. It features a cutting structure enhanced with high-grade tungsten carbide hard facing or superior tungsten carbide inserts,
of formulas and advanced techniques, significantly boosting the wear resistance of the reamer.
6. The pilot component is the tricone bit.
7. Seal and Lubrication: Equipped with high-performance HNBR O-ring for optimal bearing seal and superior grease for comprehensive lubrication.
8. Product Applications: Ideally suited for expansive well projects, mining endeavors, and infrastructure applications.
9: Recommended Drilling Parameters: Please note, the dimensions and number of cones are meticulously customized to meet each customer's specific requirements.
customer's requirements.
2. Advantages of Hole Opener Bits
Directional Crossing Operations are prevalent in projects where excavation is unfeasible. This sophisticated operation unfolds in three critical steps:
1. Oriented Hole Operation; 2. Hole Opening; 3. Pipe Pulling.
The hole opening stage is the most challenging yet crucial component of this process, where the choice of the appropriate hole opener, matched to the operation equipment and geological formation, becomes pivotal.
