1. Hole Opener: The Essential Element for Precision Drilling
1. Typically, drillers initiate their projects by creating a smaller pilot hole. The strategic use of a hole opener follows, enabling efficient enlargement. This technique is a standard approach in scenarios where drilling machines possess lower power or when the end-hole dimensions are exceptionally large.
of regular drilling technology when the drilling machine is lower power or the end-hole is too bit
2. Customization is our forte; we tailor hole openers and solutions to match various rock hardness, desired drilling depths,

2. Advantages of Hole Opener Bits: Unleashing new possibilities in directional crossing operations.
Directional crossing operation is a cornerstone in unexcavated projects, encompassing three essential steps:
1, Oriented Hole Operation; 2, Hole Opening; 3, Pipe Pulling.
Hole opening stands as the pivotal challenge in this sequence, demanding expert selection of hole openers based on operational equipment and formation characteristics. The choice of the right opener is crucial to overcoming this demanding task with success.
