Why are the three cone bits the most used?

Tricone drills are widely used in the well drilling industry when it is necessary to traverse softer and harder rock formations.

Due to the impact, crushing and shear of the rock when the roller cone rotates, the contact between the cone and the bottom hole is small, the specific pressure is high, the working torque is small, and the work sheet has a large full length and can be used on rocks of all kinds.

What is the working principle of the tricone drill?
Tricone bits rely on the impact of the cone when forming, crushing and sliding the shear to crush the rock.
