8 1/2"(215.9mm) TCI Tricone Bit IADC637G for Hard Rock Drilling
Tricone Roller Bits - 8 1/2''
|Cone Size||8 1/2"|
|Bearing Type||Elastomer Sealed Bearing|
|Circulation Type||Mud Fluid|
|Thread Connection||4 1/2 Reg Pin|
|Application||Hard formation with high compressive
strength ,such as hard shale,sandstone,
dolomite, hard gypsum,chert,granite,etc.
8 1/2 inches(215.9mm) tricone bit is a very regular size. Applications covers vertical well drilling like water well drilling, oil/gas well, and horizontal drilling like trenchless/No-Dig/HDD application. Besides that, (roller cones1/3, thirds) of 8 1/2" tricone bits which cone-diameter is 133 mm are widely used in foundation rock piling field.
Steel raw materials 15CrNiMo for the arm and 15MnNi4Mo for the cone, the cutting teeth which we call it Inserts or TCI(Tungsten Carbide Insert) is hard alloy for drilling hard rocks, especially the IADC637G that has conical ball shape tungsten carbide inserts or spherical shape inserts has very good performance in drilling hard rocks.
The bearing is vital to the working-life of tricone bit, we adopt the most advanced design and precise CNC machine and following API specification to warranty quality.
