Roller Cone Bits: Single Product Line
Single-cone sealed bearing bits of small and medium diameter have high life resource during deep drilling comparing to three cone analogues. Supper design hardfaced friction bearings, special cutting structure and thick cone walls guarantee accident-free drilling and high-performance in deep intervals.
The absence of gauge and shirttail make the bits superior in fast drilling of curves during horizontal and directional drilling.
Patented cutting structure of Single-cone bits consists of tungsten carbide hoof-shaped inserts with sharp rock-cutting curvilinear edge and various installation combinations. The TCI offset is 5-7 mm. For certain applications, PDC inserts can be used in combination with TCI.
To improve the durability of the cutting structure and enhance the performance, the cone body is coated with patented materials using special technology.
Lubrication system is designed to compensate grease consumption and pressure during long-term operation.
