Advantage
1. The impact resistance of the teeth is improved and the tooth breaking rate is reduced by adopting the high strength and toughness cemented carbide teeth;
2. The optimized design of tooth row number, tooth number, bared tooth height and unique alloy tooth shape give full play to the cutting ability and cutting speed of the bit;
3. Roller cone bits locked with circlips can bear high drilling pressure;
4. The anti-friction alloy is welded in the inner hole of the roller bit to improve the anti-occlusion ability of the bearing;
5. The optimized sealing compression of O-ring of NBR improves the reliability of bearing sealing;
6. The all rubber oil storage bag which can limit the pressure difference and prevent drilling fluid from entering the lubrication system is adopted to provide good lubrication for the bearing system, and ensure the normal operation of "O" ring and improve the working life of the roller bit;
7. The new grease with high temperature resistance and low wear is adopted to improve the high temperature resistance of the sealing lubrication system of the roller bit.
How to chosse the right tricone bit for yourself?
Soft formation TCI tricone bits
The soft formation TCI tricone bits are used to drill low compressive strength, very soft formations. This bit maximized to use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
Medium formation TCI tricone bits
The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Hard formation TCI tricone bits
The hard formation TCI tricone bits can be used to drill hard and abrasive formations. Wear resistance tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical shaped inserts are used in all rows to provide cutter durability and long life.
