Produce Different Sizes Of Single Roller Cone Bits For Mining Industry
1.Carbide inserts are arranged on top of the cine of single cone bit to improve wear resistance for longer working life of the bit.
2. New type of hydraulic system enhances cone and bottom hole cleaning ability to assure higher ROP of the bit large diameter active cutting conical spherical inserts are used for gage protection on bit body, so that the bit has excellent gage holding and up-reaming abilities.
3. Single cone bit is suitable for slim hole drilling operations such as reentry and sidetracking operations.
