1. Tooth palm bearing surface surfacing layer of hard alloy, cone bearing with reduced after welding together gold for silver, improve the bearing capacity and resistance to bite ability;
2, bearing type O sealing ring is wear-resistant, high temperature resistant high saturation NBR, increase the sealing ring section reduces the pressure seal, carefully designed sealing convex platform outside the improved seal reliability.
3, USES the steel ball or card lock reed cone way, card lock can endure high reed drilling pressure, steel ball to lock the can adapt to high speed.
Reamer bit, hole opener bit, reamer drill bit
1. Cutting Structure
The reamer mainly consists of four or more cones. Cutting Structure with premium tungsten carbide hardfacing or premium tungsten carbide insert of formulas and new techniques is utilized, and increases wear-resistance capability of reamer. The pilot is three cone bit ( tricone bit ) .
2. Seal and Lubrication
High performance HNBR O-ring for bearing seal and advanced grease for lubrication.
3. Product Application
It is suitable for the large size well, mining and infrastructure applications.
