How does a rotary drilling rig break the core

It uses a rotating motion to break up rock and soil. The broken material, called cuttings, is then lifted to the surface. This happens through the circulation of drilling fluid, often called "mud," or compressed air. The fluid also cools the drill bit and stabilizes the borehole.
