Rollers cone bits with cutting structure based on high-quality tungsten carbide inserts adapted to drilled formations in all applications. In our solutions, we use sealed and unsealed bearings depending on the customer’s conditions and preferences. To increase gauge protection, wear-resistant carbide inserts and hardfacing have been used. Optimised ROP is ensured by effective flushing of cutting structure and hole bottom. Sizes available: from 2-3 / 8” to 28” (711.2mm)

Possibility of drilling in various rock formations thanks to the perfectly adapted cutting structure.
Exceptional bit reliability due to superior
quality materials and optimized design of bearing system.
Outstanding reliability of the solution guarantees execution of numerous geotechnical holes.
