High quality 17 1/2" Tricone drill bit for well drilling


Product Description


Welcome your arrival!

Tricone bit is used in many fields such as Oil well, gas well, water well, etc. As a expert you know undoubtedly that Choosing a rock roller bit which has good quality reasonable price will provide you much competitive forces. So, we're not just choose things, but also in the choice of the future.

Please follow my instructions, and know more etails about the rock roller bit—of course and your need.


The use of tricone bit

1.Soft formation tricone bit

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.

2.Medium formation tricone bit

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.

3.Hard formation tricone bit

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.

4.Medium hard formation tricone bit

The medium hard formation TCI tricone bits features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability.


Detailed  introduction for tricone bit


The structure of tricone bit

1.Cutting Structure of tricone bit

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

2.Gauge Structure of tricone bit

Multiple gauge protection with gauge trimmers on 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.

3.Bearing Structure of tricone bit

High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.

4.Seal and Lubrication of tricone bit

The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
