Description:
Izhevskiy Mashzavod Trading House offers roller cone bits from the Czech company New Rock Bits (NRB). New Rock Bits feature a unique design that allows for flexible configurations of cutting structures, bit protection, and bottomhole cleaning systems. New Rock Bits' bearings ensure specified bit life parameters for drill string rotation speed, weight-on-bit, borehole section length, as well as drilling fluid composition and air mixture parameters for bottomhole cleaning or borehole reinforcement. The bit stabilization system allows them to be used for drilling wells of any complexity.

Drilling results
The Doloto 155.6 mm N23 (type ST-CN) Rainbow series made it possible to ensure a hassle-free borehole drill throughout to the design mark.
The average mechanical pass rate was 29.9 m/hr and exceeded the expected result by almost three times. The dynamic changes of the mechanical pass rate values were within acceptable limits due to the self-tightening of the milled teeth balls during wear during the drilling process, which allowed to optimize the failure mechanics.
The hammer support bearings maintained full performance after drilling was completed without critical wear of the working surfaces.
Due to the reduction in total drilling time the cost of works was reduced by 218%.
Thus, the use of the Rainbow series portion ensured to achieve and exceed the target of reducing costs in drilling artesian wells in the Dmitrovsky district of the Moscow region
