ISO CE Sealed Steel Tooth Tricone Rock Bits for Water / Oil / Mining Well Drilling 12inch 305mm
Application
12inch API Sealed Steel Tooth Tricone Drill Bit for Rotary Mining Drilling IADC 214 / 215 / 216 / 217 is suitable for various formations, and achieves high RPM under low to medium WOB application
Characteristics
Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
Gauge Structure
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Bearing Structure
High precision roller bearing with two thrust faces. Ball lock the cone.Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
