11 5/8" IADC 537G Tricone Cone Bits With MnNiMo Steel Drill Bits
For Water Well And Oil Gas
We offer verious new steel tooth and tungsten carbide insert (TCI) tricone bits in sizes from 3 1/2" – 26", with open or sealed bearings, regular
or jet circulation, and a wide range of additional custom features
for ideal performance in any formation. Tricone bits can be customized to optimize penetration rates and bit life in
particular formations and under specific operating weights and
rotation speeds.
Steel teeth or carbide inserts come in a variety of shapes, sizes,
and grades of tungsten carbides to address specific drilling
conditions. TCI bits offer increased durability over steel tooth bits but also carry a
higher cost.
