Soft Formation TCI Tricone Bits
The FL 415 tci bits are used to drill low compressive strength, very soft formations. TCI bits 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 balling in sticky formations .

Description

Main structure features

1.journal bearing. hardfaced head bearing surface.cone bearing inlaid with friction reducing alloy and then

silver plated.the load capacity and seizure resistance of the bearing is greatly improved.

2.o-ring seal is made of the more wear resistance high saturated buna- N with the section and precissely designed sealing flange in the cone sealing area increased the reliability

of the seal.

3.the bit bearing is ball which can be applied to high rotary speed drilling.

4.all rubber compensator is used which can provides the bearing system with good assurance of lubrication.

5. new type of grease that can sustain high temperature up to 250C is utilized.

6.high wear resistance and excellent cutting ability of the insert bit are given full play by using carbide

compacts of high strength and high touhness in combination with optimized comjpact numbers and rows,

the exposure height and special shaped compacts.
