1. Tungsten carbide insert tooth, sealed and gage protection journal bearing
2. Meet strictly of API and ISO standard
Production Description:
These tungsten carbide insert bits are used to drill soft formation with low compressive strength and high drill ability, such as shale, clay, sandstone and soft limestone, etc.
1. Tungsten carbide insert tooth, sealed and gage protection journal bearing, hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver plated. The load capacity and seizure resistance of the bearing is greatly improved
2. O- ring seal is made of the more wear resistance high saturated buna-N with the section and precissely designed sealing flange in the cone sealing area increased the reliability of the seal.
3. The bit bearing is ball which can be applied to high rotary speed drilling.
