What are the advantages of diamond other than longer life?
Accuracy: The diamond coating is very thin, but very hard, and tools don t change significantly in size during their life. For instance, the radius on an endmill will change by about 10 microns (0.0004″) from when new to the point that it is worn out. Speed: Diamond tools can typically be run at two to three times the surface speed of carbide tools. Dry cutting: Diamond tools can often convert an operation from wet to dry machining, providing a significant saving in overall machining costs.
