9 7/8 S832 Mining Rock Bit Operation Instructions

Brief Introduction:

The strength and wear resistance of inserts are improved by using carbide inserts with high strength and high wear resistance. Surface of the high precision bearing heat improve the service life of the bearing is further extended by adopting harder and more wear resistant material for it can avoid air counterflow and dust working into bearing when the air-compressor stop working accidentally, and separate air and water in order to avoid water entering into bearing when it works normally to prolong the life of bearing.

Uses and Applicable Ranges of the Bit

Uses: The bit used for air drilling, e.g., for drilling operations in open coal mine, iron mine and non-ferrous mine.

Applicable ranged: The bit is applicable for drilling hard and very hard formations with high compressive strength and high abrasiveness, such as magnetite quartzite, quartzite, granite, hard sandstone, dolomite, chert and ironstone, etc.
