6 3/4 S632 Mining Rock Bit Operation Instructions
Brief Introduction::
The bearing strength and wear resistance of inserts are improved by using carbide inserts with high strength and excellent toughness.
Through proper surface heat-treatment, the load capacity and service life of the high precision bearing are greatly improved.
The service life of the bearing is further extended by adopting harder and more wear resistant material for thrust bearing.
Uses and Applicable Ranges of the Bit
Uses: The bit is used for air drilling, e.g., for drilling operations in open
Coal mine, iron mine and non-ferrous mine.
ApplicableRanges: The bit is applicable for drilling medium hard formations with high compressive strength or with high abrasiveness, such as limestone, sandstone, dolomite and chert, etc.
