Our TCI roller cone bits are used for rotary drilling in hard and abrasive rock formations. The cones are equipped with tungsten carbide inserts that break and crush the rock as they roll over the bottom of the borehole.

Our TCI roller cone bits are available in various designs for different rock formations.
