Advantages
Best price and high quality
Bearing types: 1. Sealed bearings and non-sealed bearings. 2.
Metal-sealed journal bearings. 3. Rubber sealed journal bearings
Cutting structure: All surfaces of the back cone and teeth are
hardened, which improves the shape of the steel teeth and welding
materials, showing higher teeth
Application structure: low compressive strength and high
drillability softness, such as shale, clay, salt layer, etc.
All our activities have obtained ISO 9001:2008 and API
certification for products and services. At the same time, mature
production technology can ensure that the quality meets
international requirements.

Used in
It is suitable for large-scale wells, mining, soft rock with low
compressive strength and high drillability, such as shale, clay,
salt formation and infrastructure applications.
Features
Cutting structure
The reamer is mainly composed of four or more cones. The use of
high-quality tungsten carbide hard surface or high-quality tungsten
carbide blade formulations and new cutting structures can improve
the wear resistance of the reamer. The pilot is three cone drill
bits.
Sealing and lubrication
High-performance HNBR O-ring, used for bearing seal, high-grade
grease, used for lubrication.
