Opener Drill Bit/Rock Reamers/Assembled Bits
1. Cutting Structure
The reamer mainly consists of four or more cones. Cutting Structure
with premium tungsten carbide hardfacing or premium tungsten
carbide insert of formulas and new techniques is utilized, and
increases wear-resistance capability of reamer. The pilot is three
cone bit( tricone bit ).
2. Seal and Lubrication
High performance HNBR O-ring for bearing seal and advanced grease
for lubrication.
3. Product Application
It is suitable for the large size well, mining and infrastructure
applications.
4. Main Availability, ( Bit sizes and cone types can be customized as you special
order).
water bore hole drilling HDD reamer tricone bits opener
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.
