Roller Cutter Bit / Roller Cone Bit
What is a roller bit?
Definition of roller bit. i. A rotary boring bit consisting of two to four cone-shaped, toothed rollers that are turned by the rotation of the drill rods. Such bits are used in hard rock in oil well boring and in other deep holes down to 5,000 m and more.
What are the two basic kinds of roller cone bits?
There are two main types of roller-cone bits, steel milled-tooth bits and carbide insert bits.
How does a tricone drill bit work?
These drill bits employ high pressure air that travels down the air passages into the tricone bearing helping to lubricate, cool and remove pieces of particles from the tricone. The ability to self-clean, lubricate and cool the Tricone bit is a strong competitive advantage for the air-cooled roller bearings.
