12 1/4 API Steel Tooth Rotary Rock Roller IADC117 Tricone Drill Bit
For Well Drilling
Tricone drill bits has been in continuous use in the oil & gas
industry, and is still being improved!
We have a wide selection of tricone bits - there’s a bit for every
application.
Our product line can be configured to use tungsten carbide insert
(TCI) bits and steel tooth bits for the toughest drilling
applications.
Product Description:
KSQ tricone bit used for geoloical prospecting, development of oil
and gas,drilling water wells,blast holes and making holes for
seismic prospecting,construction engineering.
Product Advantage:
1.High grade tungsten carbide inserts in heel and gage rows, which
greatly increase gage protection ability, also prolong the service
life, it is suitable for abrasive formation drilling.
2.The steel body with high strength after heat treatment.
3.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.
4.Threads are machined with CNC machine to keep a precision and
dimension. A thin layer of heavy duty grease is applied to prevent
rust.
