F/ FC Series Tir-cone Rock Bits For Oil-well Drilling
Features:
1. This series applies float ring that have high strength and processing precise, and prolong the bit bear life.
2. New designing lubrication reservoir structure enhances lubrication oil compensation ability of bit bear, and reduces wear of bear pair.
3. Gauge protection structure of raised design leg reduces friction from the back of leg to well wall, and gains high drilling efficiency.
4. Gauge teeth added on the cone enhances ability of cutting well wall.
