Horizontal Directional Drilling Downhole Soil Hole Opener
Larger Bearing And Cutters Dramatically Soil Hole Opener Extended Life Downhole
Introduction
HDDD hole openers for horizontal drilling
Horizontal reamer, also known as HDDD reamer, is used to expand the pilot hole of horizontal directional drilling (HDDD) - HDDD is used when grooves and excavations are not practical. This drilling technique allows drilling underground in a manipulable trenchless manner.
Advantages
Cutting Structure
Reaming bit mainly consists of four or more cones. Main cutting tooth is Tungsten Carbide insert tooth and steel tooth welded new-type wear-resistant alloy. High quality tungsten carbide tooth of new formula and new technique increases the service life of reaming bit. The pilot is roller cone bit or drag bit.
Seal and Lubrication
The bearing seal applys high performance O-ring seal or metal sealed bearing and imported lubrication grease special for bit.
Product Predominance
It is applied in the big size casing well section, mining and infrastructure building drilling.

The main structure features
Reamer with interchangeable tool was developed for large diameter HDD projects where extending downhole life is critical. Larger bearings and tools significantly extend downhole life compared to smaller, conventional types of tools.
Replaceable milling sets are available in TCI and grinding teeth to accommodate a variety of rock formations. All bits have 3-6 cutters and can be drilled in 4 different sizes.
All tool bearings are metal sealed. Tool locks are used to prevent cutting tools from falling off.
It can provide 400-2000mm hole opener.
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.
