|---|---|
The 4 3/4''120mm IADC 217 mill tooth tricone roller bit is designed for soft and medium formations. Its rubber-sealed bearing ensures smooth operation and durability. This bit is suitable for drilling in clay, shale, sandstone, and similar formations. It is widely used by manufacturers and suppliers for water well, oil, and gas exploration. Its reliable performance reduces costs in drilling projects. HJ Bit offers customization for aftermarket solutions to meet specific requirements.
This product is available for sale, ensuring high-quality results in challenging conditions.
Bearing Structure: High-precision journal bearings with dual thrust faces. Cone bearings are silver-plated and inlaid with friction-reducing alloy, improving abrasion resistance and enabling high-speed rotary performance.
Gauge Protection: Tungsten carbide inserts placed in the gauge area reduce wear and ensure extended stability and lifespan of the bit.
Nozzles: Sturdy nozzles with superior flow capacity optimize fluid distribution for effective cone cleaning and enhanced drilling efficiency.
Hardfacing: Tungsten carbide hardfacing is applied along the shirttail and bit leg, providing additional protection in high-speed and abrasive drilling environments.
Seal and Lubrication: Rubber-sealed bearings use HNBR O-rings, ensuring reliable sealing and lubrication under extreme conditions. High-quality bit grease enhances bearing longevity and reduces pressure differentials.
