Hard Formation Dth Hammer Drill Bits Tungsten Carbide Inserted Tricone

Hard Formation Rock Tungsten Carbide Inserted Tricone Bits/Roller Drill Bits

Description of Tricone Bits:

The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.

1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate the upward flow of drilling cuttings and improve ROP.

2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.

3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit.

4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.

Cutting Structure

The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit

Gauge Structure

Multiple gague protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life.

Bearing Structure

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

Seal and Lubrication

The advanced metal seal package consists of two metal seals and two elastic energizers.Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force,and achieves the bearing seal.In the drilling,metal seals 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.

Product Application

It is suitable for down hole motor and high speed applications
