Hot Sell Mining Series Tungsten Carbide Coal Drill Bits for Mining Tools

We gingte produce various tungsten carbide drill bits for mining tools.The button bits slot into the head of the boring machine.The individual carbide tips grate against the rock face and shuck off rock chips.Carbide alloys last longer then steel alloys, are more corrosion resistant and withstand greater amounts of heat. Some mining operations involve spraying water to keep down dust and cool off the drill tips. Steel tips rust fast in this environment,so carbide tips are used when possible.Cemented carbide mine tools are produced by a joining process called brazing, which is a well-established commercial process capable of producing strong joints. It is widely used in industry because of its ability to join most metallic materials, including dissimilar metals.We supply a lot of types of carbide bits,they are used in coal cutter drilling tools, Mine machinery tools. Cemented carbide Mining Button Bits are widely applied for Rock tools, mining tools for use in quarrying, Mining, Tunnelling and Construction.
