Inserted Tooth Roller Cone Bit IADC517

Cutting Structure

Adopting a new formula and new process of high-quality tungsten carbide, the special offset wedge-shaped inserts can more effectively break rock and remove cuttings, improving drilling efficiency and service life.

Gauge Protection

The heel-row trimming inserts and the back-cone gauge inserts more effectively protect the bit, making the borehole more regular and smooth and extending the bit life.

Bearing

High-precision sliding bearing with two thrust faces, ball locking mechanism, bearing surface inlaid with wear-resistant alloy and silver-plated. It has strong wear resistance and is suitable for high-speed rotation during drilling.

Sealing and Lubrication System

High-quality HNBR rubber sealing rings are wear-resistant and high-temperature resistant, which will increase the reliability and durability of the bearing seal during drilling. The compensated sealing system and high-quality grease can limit the pressure differential, greatly improve lubrication reliability, and more effectively protect the bearing mechanism.

Applicable Formations

Suitable for undercompacted formations with good drillability, such as mudstone, coarse sandstone, limestone, and a small amount of gravel-bearing interbeds.

Our company can produce bits of this model in different sizes according to customer requirements.
