F/FC Series Tri-cone Rock Bits for Oil Well Dilling

The main structure features:
-This series applies float ring that have high strength and processing precise, and prolong the bit bear life.

-New designing lubrication reservoir structure enhances lubrication oil compensation ability of bit bear, and reduces wear of bear pair.
-Gauge protection structure of raised design leg reduces friction from the back of leg to well wall, and gains high drilling efficiency.

-Gauge teeth added on the cone enhances ability of cutting well wall.
