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.
