Product Details
The main structural features
1, the use of high strength and toughness carbide teeth, improve
the impact resistance of teeth to reduce the broken tooth rate;
2, Optimized design of the number of teeth, the number of teeth,
tooth height and unique alloy tooth profile, give full play to the
bit cutting ability and cutting speed;
3, the use of snap-lock locking cone, can withstand high-pressure
drilling;
4, cone welding inlay reduction alloy, improve anti-bite bearing
capacity;
5, the use of highly saturated nitrile rubber O-ring, the optimized
seal compression to improve the reliability of bearing seals;
6, the use of all-rubber reservoir can limit the pressure
differential and prevent the drilling fluid from entering the
lubrication system, providing a good lubrication for the bearing
system and ensuring the normal working of "O" ring seals and
increasing the working life of the drill bit;
7, the use of new low-wear grease, drill seal lubrication system to
improve the ability of high temperature.
