Tricone drill bit

Tri-cone Bit mainly used for large-scale opencast mining, such as opencut coal mine, copper, molybdenum ore , iron mine and various nonferrous metal mining, have high drilling efficiency and low cost. According to the company\'s developing strategy, our tri-cone bits have revised thrust bearing structure, inverted valve and dorsal metacarpal diversion structure, which we have property right on. Up to now, based on the demands of customers, we have developed two standard series, more than fifty products, which can be used for different formations.
