Cutting Structure
Conic&chisel insert improved the bit aggressivity and abrasive resistance.Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.
Bearing Structure
High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head 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.
Gauge Structure
The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.
Seal and Lubrication
The bearing seal is adapting the high quality HNBR O-ring. The better seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.
General application
Soft Formation TCI Tricone bits
Are used to drill low compressive srength ,very soft formations.Tci bit maximize the 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 baling in sticky formation.
Medium formation tci tricone bits
Feature 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 harf formations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Medium hard formation tci tricone bit
Feature 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.
Hard formation tci tricone bits
Can be used to drill hard and abrasive formations. Wear-resistant 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.
