Roller bearing bits utilize three cones spinning independently. They are most often used to drill oil, gas or shallow water wells. 2. Sealer roller bits have a seal that protects each drill bit from damage during the drilling process. Although the seal will eventually be worn away from constant use, this model can still be employed as a roller bearing bit in future projects. 3. Sealed journal ...

TCI Roller Tricone Rock Rolling cutter bits, which some may also call roller cone bits or tri-cone bits, have three cones. Each cone can be rotated individually when the drill string rotates the body of the bit. The cones have roller bearings fitted at the time of assembly. The rolling cutting bits can be used to drill any formations if the proper cutter, bearing, and nozzle are selected.
