Roller Cone Bits: Standart Product Line
Standart Product Line:
These bits are manufactured mainly in Volgaburmash manufacturing facility in Yekaterinburg (Uralburmash)
The products of this line are open journal or roller bearing bits with steel teeth or tungsten carbide inserts.
They are designed for a wide range of applications: drilling with low speed turbine, downhole hydraulic motor or for rotary drilling. To increase the ST bits’ life, steel teeth are hardfaced with wear-resistant tungsten carbide based material. Depending on the rock hardness, either side surfaces or side and end surfaces of steel teeth are hardfaced.
The gauge may be protected with tungsten carbide inserts. For additional protection against gauge loss, a near gauge of tungsten carbide inserts may be applied. Shirttail could be hardfaced along its leading edge.
