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)

Single cone bit is a bit slow, that cone drill bit of speed than the speed of smaller, mainly chaotic cutting rock, suitable for high-speed, high pressure drilling wells sidetracking the old, old wells deepened so slim hole drilling.
1. Applications more widely applicable not only to lateral drilling, and can be used in deep wells.
2. Working torque than the PDC drill bit in the same conditions of pressure and lower strata can reduce the problem of small size drill expansion button to avoid mine accidents.
3. Single cone bit with both three-cone bit and PDC bit of advantage, there is a difference between the two Surrounded by a shortage of more than three-cone bit more suitable for large plastic formation, but also can be applied to PDC bit difficult to deal with hard interlayer, and other complex formations.
4. With the downhole drill motor to achieve high speed and special drilling needs.
5. Size: various sizes 3 3 / 4 "(95.3mm) --- 6 1 / 8" (155.6mm

 5) TCI cone bit
1. Covers almost all IADC codes.
2. Rapid delivery time
3. Meet with API Spec7-1 Standard 

6)Please specify the following on enquiry,
1.Bit diameter
2.Drilling formation
3.guide bit/pilot bit diameter
4.cutters type
