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.
