The Drill String: Mix a Drill Bit and Drill Pipe, and Stir
The drill bit and drill pipe together make up the drill string, which transmits the torque from the rig to the bit through 30-foot sections of pipe, all to break up rocks under the seafloor.
Drill bits are specialized for a variety of tasks and rock formations. Certain bits are only used to fish out tools accidentally dropped down the bore, while others grab sections of drill pipe that come loose when the drill string breaks.
The string is hollow, which allows drilling mud to be pumped down to the drill bit. This assists in lubricating the moving parts, as well as preventing other liquids in the earth from entering the well bore.
