Horizontal Directional Drilling hole openers are also known as HDD reamers which used to enlarge the pilot hole in Horizontal Directional Drilling (HDD).HDD is used in trenching and excavating is not practical. This drilling technology allows for a steerable trench-less way to underground. There are three stages: The first stage is to drill a small diameter pilot hole. The second stage is to enlarge the hole with a larger diameter cutting tool called an HDD Reamers, Rock Reamer or Hole Opener. The third stage is inserting the casing pipe or other product into the enlarged hole. | |||
