steel tooth roller bit

Product Description:

Size from 3 7/8" to 26" Covers almost all IADC code. Good quality and after-sale service Meet with API Spec7-1 &ISO 9001: 2008 steel tooth roller bit 1>Cutting Structure The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit. 2>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 hard facing on the shirttail increases gauge holding capability and bearing life. 3> 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. 4>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. 5>Product Application It is suitable for various formations, and achieves high RPM under low to medium WOB application.
