Horizontal Hole Openers, also known as HDD Reamers, are used to enlarge the pilot hole in
Horizontal Directional Drilling(HDD) - HDD is used when trenching and excavating is not practical.
This drilling technology allows for a steerable trenchless way to drill underground.
There are three stages:
1>the first stage is to drill a small diameter pilot hole.
2>The second stage is enlarge the hole with a larger diameter cutting tool called an HDD Reamer,
Rock Reamer or Hole Opener.
3>The third stage is inserting the casing pipe or other product into the enlarged hole
All sizes and IADC codes of drill bits are available.
Special requirements of different models can be customized.
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.
