Coatings applied in cutting tools have been proved to be very effective. There are several objectives that coatings must achieved.

The objectives are to:

Cut costs 
Enhance productivity
Increase manufacturing reliability 

To attain these objectives, the focus must be on tools which fulfill ever more stringent requirements. A key role is played by the coating which interacts with the base material and the tool geometry to achieve superior performance. Princo's coatings can sufficiently increase the service life of tools several times than non-coated tools, often with a concurrent improvement of cutting data. They offer reproducible process behavior at a high performance level.
