500mm Reamer Bit HDD Hole Opener For Hard Rock Drilling
HDD Hole Opener Reamer Bit Hole - Opener For Hard Rock Drilling
Introduction
The reaming bit is mainly composed of more than 3 cones. The cutting structure adopts high-quality tungsten carbide cemented carbide inserts for surfacing welding, which adopts new technology and new formula, and improves the wear resistance of the reamer.
1. Main size: general drill diameter: 311mm, 346mm, 500mm, 800mm, 900mm, etc., various sizes can be customized
2. Purpose: In the construction site and bridge construction, the hole opener can expand the small well hole to large diameter. Highway construction, railway construction, etc. The drill bit is suitable for different complex formations, shale, limestone, pebbles, etc.
3. Cutting structure: The hole opener always has multiple cones. The drill bit cone is separated from the tri-cone drill bit and welded to form a large-diameter drill bit, and the pilot device is connected with the hole opener.
Features
1) Drill Bit Connection made according to API standard.
2) We can adjust the bit size according to your rig.
3) The best result can be obtained by using the steel-tooth bit in
the soft stratum.

Apply to Construction, Water Drilling, Mining, Horizontal
Directional Drilling, Geothermal and Environ-mental.
Advantages
1. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit
has good gauge protection and up drill capability.
2. Bearing Structure
High precision journal bearing. Balls lock the cone.Hardface heard
bearing surface. Cone bearing inlaid with friction-reducing alloy.
Abrasion resistance and seizure resistance of the bearing are
improved. Compared with three cone bit, the leg bearing is bigger,
so it can receive higher WOB and high reliability.
3. Hydraulic Design
Small angled watercourse design increased the shirttail thickness
and can effectively prevent the watercourse erosion.Optirnized
hydraulics structure improves the clearing capability and increases
ROP.
4. Product Application
It is suitable for sidetracking, deep well drilling and old well
