Roller cone drill bit
17-1/2” IADC 117

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).

Exceptional drilling performance achieved by optimally selected cutting structure geometry in combination with effective flushing system.
Exceptional bit reliability thanks to top quality materials and optimized design of bearing system.
Guarantee of drilling long intervals while maintaining proper well geometry due to premium materials.

Designed for drilling in very soft formations, unstratified, poorly compacted rocks such as shale clays, clays, poorly compacted clays and sandstones, marl limestones, salts, gypsum, hard coals, iron ores.
