High Quality 6 1/2" Tungsten Carbide Insert IADC 837 Tricone Roller Drill Bit
High Strength Tricone Rock Bit 6 1/2" For Soft To Hard Formation
Tricone drill bits have been in continuous use in the water well, oil & gas industry, and continue to be improved through ongoing innovation. We offer a comprehensive selection of tricone bits designed for every application, including tungsten carbide insert (TCI) bits and steel tooth bits for the most demanding drilling conditions.
Tricone bits deliver faster cutting speeds and extended service life across all ground conditions, particularly in varying formations. They provide higher penetration rates and superior drilling quality.
The 6 1/2" blast hole bits are engineered for drilling soft to medium hard formations with rock compressive strength. Suitable formations include shale, limestone, quartzite, slate, sandstone, and granite.
- Very soft formations with low compressive strength and high drillability
- Shale, clay, sandstone, gravel, and similar materials
