TCI bits

Tungsten carbide inserts (TCI)

NRB roller rock bits have improved performance characteristics. In the design of the cutting structure has been used optimizing of the distribution of cutters and shape of cones taking into account the features of the mechanism of destruction of various types of rocks. Cooling of bits and purification downhole bottom have been adapted for different systems of drilling mud and/or air circulation.


ST bits

Steel toothed (ST) bits

Drill bits with milled steel teeth have a hardfacing with tungsten carbide allow on the teeth to a improving the abrasive wear resistance and extra protection of cones gauge by tungsten carbide inserts, which provide high ROP. Drill bits with tungsten carbide inserts have highly abrasive and impact wear resistance and they provide enhanced footage in the drilling of any rock formations.
