A cutting tool must maintain a certain edge and profile to efficiently produce a chip without too much heat. If the tool bit is only slightly harder than the workpiece, the tool will wear out after cutting only a few pieces and the pieces likely will be rejects.

And your question is?? Your question is a statement, not a question. It doesn't have to be 35%-50% harder, this is just a suggestion for best results. Case in point: Ceramic is on a scale of 10 in hardness a 9. What is used to machine ceramic is diamond which is a 10. Knowing the percentage of the materials you are working with allows one to select the proper speed, and feed to do the job without crashing the machine. Have Fun!
