Medium Formation TCI Tricone Bits

The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design

provides a fast drilling rate and added cutting structure durability in medium-to-medium hard for-mationes.

The HSN rubber O-ring provides adequate sealing for bearing durability.

HJT517J

517

It is used for low compressive strength and soft formation of high drillability, such as, shale, clay, sandstone, soft limestone, halite, gypsum etc

Its structure is Large-diameter side top row of teeth within the spoon-shaped, and wedge-shaped outer row of teeth. Its teeth are different height and the margin is not different distance, also it increases a row of trimming teeth between the back conical teeth and outer row of teeth.

FA series bit for oil well drilling

1. Floating bearing structure. The floating elements are made of new materials with high strength, high elasticity,

high wear resistance and can endure high temperature, and bearing surface is treated with solid lubricant.

This decreases the relative linear velocity of the bearing couple and reduces the temperature of the friction

surfaces, which result in improved reliability and working life of the bearing under large WOB and high RPM

conditions.
2. The O-ring seal is made of high-saturated buna-N with good wear resistance and which can endure high temperature. The increased seal section reduces

unit pressure on the seal, and finely designed sealing flange increases reliability of the seal.
3. Ball locked cone, suitable for high rotary speed.
4. All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering

the lubrication system and this provides the bearing system with good assurance of lubrication.
5. New type of wear resistant grease that can sustain high temperature up to 250ºC 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 toughness in combination with optimized compact numbers and rows,

the exposure height and special shaped compacts. For steel tooth bit, the tooth surface is hardfaced with

new type of wear resistant material and thus extended working life of the cutting structure while still maintaining

high ROP.

Product predominance: FA series tri-cone bits are O-ring sealed floating bearing products. This series of bits are suitable for high RPM and high WOB drilling applications and they can be used to drill formations from very soft to very hard by selecting proper cutting structures.

Available types of FA series tri-cone bits: FAT127, FA437, FA447G, FA5117G, FA537G, FAT617G, FAT637G and FAT737G, etc
