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)
Ultra fast, reliable drilling results thanks to the optimal cutting structure.
Extended bit life in air drilling applications thanks to latest bearing cooling technology.
Extended service thanks to TCI inserts on the gauge protection.
Designed for drilling in medium-compacted rock such as: medium-hard shales, anhydrites, marbles, sandstones with clay silica binder, marl dolomites, clay siderites, and in medium-hard compacted rocks such as: hard crystalline limestones, hard anhydrites, compressed limestones.
