Bicentric and concentric bits

The design of the pilot and reaming parts allows for efficient reaming, reducing the likelihood of whirling.

The body of bicentric and concentric bits is integrally-machined design.

Overall dimensions are selected to provide the best steerability of assemblies.

Bicentric bits

Bicentric bits make it possible to drill wells with a diameter larger than the drift diameter of the wellhead equipment, previously run casing and drilled intervals.

The design features of bicentric bits provide good controsteerabilityllability, high ROP and high-quality reaming.

Concentric bits

Concentric bits make it possible to drill wells with simultaneous reaming of the wellbore throughout the entire interval.

Bits of this line have a carefully balanced cutting structure, which minimizes the wear of cutters and casing strings when drilling out mountings.
