There are five primary reasons for using coating tools: to increase wear resistance; to increase oxidation resistance; to reduce friction; to increase resistance to metal fatigue; and to increase resistance to thermal shock.
When cutting tools are properly coated and perform as designed, the result for the end user is higher cutting data, longer tool life and the possibility of dry machining.
There is a lot of time, energy, science and thought that enters into the coating of a cutting tool. A cutting tool manufacturer's goal is to provide a product to help the user produce their parts faster and more accurately.
