Main Features

 The Advantages of Using a Tri Cone Over Other Drill Bits

1>There is a Tri Cone suitable for any rock formation

2>Tricone bit is versatile and can handle changing formations

3>Tri Cones are reasonably priced, long lasting and have an efficient drilling rate

4>The roller cones have high end sealed bearings; extremely high quality tungsten carbide and diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.
Detailed Images

Gauge protection

Special inserts are strategically arranged on head to effectively reduce head wear in abrasive fromation and directional and horizontal wells and exrend bit life

Cooling system

The nozzles is very important part in the life of a bit, bit hydraulics are controlled through these nozzles, it is also heat treatment for more strength and stability.

Extremely high quality tungsten carbide

High effectively cutting ability abd strong anti-breaking ability , which can increase ROP and improve service life of bit effectively

Metal sealed journal bearing extend cutter

The bit can achieve longer service life and higher reliability 

Body and Welding

The steel body with high strength after heat treatment
The three legs welded together with quality electrodes to ensure stability in structure. To further enhance the stability,
the bit goes through heat treatment to relieve stresses after welding

Product Application

Petroleum & gas ,water well ,mining ,oil field, construction,geothermal, directional boring, and underground foundation work
