Cemented Carbide Mine Tools

Mining machines use cemented carbide mine 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.
