Roller cone drill bit
9-7/8” IADC 211

Roller cone bits with cutting structure based on milled teeth coated with wear- resistant hard facing, adapted to the drilled formations in all applications. In our solutions, we use sealed and unsealed bearings depending on the client’s preferences. Superb ROP is ensured by the effective rinsing of cutting structure and bottom of hole. The diameters available range from 2-3/ 8 ”(60.5mm) to 42” (1066.8mm).

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
Perfect quality/price ratio.

Designed for drilling in medium-hard formations, and abrasive rocks such as: sandstones intersparsed with streaks of quartz, hard limestone or chert, congloremates, with limestone, ferruginous or silica binder, crystalline dolomites, hematite ores, siderites, limonites, hard shales.
