8 1/2" Steel Tooth Tricone Bit IADC 217
Designed for water well, oil and gas drilling applications, this tricone rock bit delivers superior performance across various formations.
Product Overview
The tricone rock bit is the industry's most widely used drilling bit. Its design features cutting teeth that alternately contact the bottom of the hole, resulting in small rock break torque and high specific pressure for efficient penetration into formations. The extended working edge length reduces wear while maintaining performance across soft to hard formations.

Applications
This tricone bit is engineered for oil and gas wells, water wells, and geothermal well drilling. Manufactured to oil drilling bit standards, it offers extended service life, high drilling efficiency, and reduced operational costs.
Key Features
- Tungsten carbide compacts in the shirttail protect the leg and body in abrasive formations and deviated or horizontal wells
- Additional tungsten carbide inserts in the gauge reduce wear in abrasive formations, enhancing stability and bit life
- Advanced shirttail protection reduces thermal effects on sealing, improving durability and rate of penetration
- Optimized for very soft formations with low compressive strength and high drillability, including clay, mudstone, gypsum, and soft limestone
