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. Feature of PDC reamer bit 1.Which is a steel body PDC bit using arc-type double rows spiral design with seven blades,long parabolic crown structure,the rational allocation of different functions of the small size of the cutters. 2.Heavy cutter layout and high wear wide gauge design,effectively improve the PDC bit impact resistant and abrasive. While using a dynamic flow simulation technology to optimize the hydraulic design of the PDC bit.

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.
