Steel tooth Rock bit--7 7/8"GS117

Tricone bit is mainly used in drilling, exploration, petroleum and trenchless as pilot bit. According to cutting material, Tricone bit can be divided into TCI bit and Steel tooth Bit. 
Cutting Structure
High quality tungsten carbide steel teeth with unique wear/compact resistance.
Gauge Structure
Enhancedgauge protectionwithhardfacing on the shirttail, strengthenedleg with special insert tungsten carbide.
Bearing Structure
High precision rollingbearing,hardfacedbearing surfaceand bearing roller. Cone bearing inlaid with friction reducing alloy and then silver-plated,made the rotating more stability, safety and durability.
Steel tooth drills are suitable for extremely soft formations with low compressive strength and high drillability such as clay, mudstone, chalk, etc. They are also suitable for medium strata with high compressive strength, such as soft shale, anhydrite, medium soft limestone, medium soft sandstone. Medium stratum with a hard interlayer.
