Roller cone drill bit
5” IADC 633

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)

Drilling costs optimization thanks to the possibility of full intervals drilling.
Flexible use of drill bits for various drilling equipment.
Effective cleaning of the bottom of the hole by using optimal flushing system

Designed for drilling in medium hard and abrasive rocks such as: sandstones with srteaks of quartz, hard limestone or chert, conglomerates with limestone, ferruginous or silica binder, crystalline dolomites, hematite ores, siderites, limonites, hardhard shales
