Tricone Bits
As a kind of commonly used rock drill bit, our tricone bits are widely applied to the mining of large-scale strip mine, such as open pit coal mine, iron mine, copper mine, molybdenum mine and other non-ferrous metal mines. As a kind of carbide tipped drill bit, our tricone bits feature high drilling efficiency and low cost, and can be perfectly applied to different rock stratum ranging from soft to extremely hard.
According to our development strategy and product positioning, we have exploited a number of tricone bits with our proprietary intellectual property right, for instance, the new type thrust bearing structure, new type check valve structure, new type gage bevel protection and sealed bit for mining. We currently have developed 3 standards, 12 specifications and more than 200 types of tricone bits conforming to the requirements of customers from home and abroad.
