IADC537 tricone drill bit is suitable for soft to medium rock formations with high compressive strength, such as hard shale, limestone, sandstone, dolomite.
The bearing structure of a tricone bit is critical for ensuring the bit's durability and high speed operation. It includes:
High Precision Journal Bearing: With two thrust faces, this design allows for precise rotation and load distribution.
Ball Locked Cone: This secures the cone to the bearing pin, ensuring stability during drilling.
Hardfaced Head Bearing Surface: This provides a wear-resistant surface that can withstand the high pressures and friction encountered during drilling.
Cone Bearing: Inlaid with a friction-reducing alloy and then silver-plated, this enhances the bearing's resistance to abrasion and seizure, making it suitable for high rotary speeds.
Using a new formula of tungsten carbide inserts and insertion techniques, the mechanical properties of the cutting teeth are reinforced for better cutting performance.
The gauge structure is designed to protect and maintain the borehole size with:
Multiple Heel Position with Gauge Trimmer: Located on the heel, this feature, along with tungsten carbide and hardfacing on the shirttail, strengthens the gauge protection.
Strengthened Spear Point: This enhances the gauge protection by providing additional support and resistance to wear.
