Tricone Bit IADC437 TCI tricone bits TCI Drill Bit

Hardfacing
Tungsten carbide particle hardfacing is applied liberally along the shirttail
and extended up the leading edge of the bit leg for additional protection in
high-speed, directional or abrasive applications
 
Shirttail Compacts
Tungsten carbide compacts in the shirttail protect the leg and body in abrasive
formations and deviated or horizontal wells.
 
Gauge Inserts
More tungsten carbide inserts are placed in the gauge to reduce the wear in the
abrasive formation. It can protect gauge and increases the stability and life
of the bit.
 
Teeth
The teeth are composed of premium tungsten carbide and some other elements, our
engineer fine-tuned the compacts to match specific formations and drilling
applications.
 
Nozzle
Optimized flushing system including three combined nozzles, balances fluid
flow, allows effectively cleaning bottom-hole zone and anti-balling.
