These are much sought after by engravers of gems and are inserted by them into iron tools because they make hollows in the hardest materials without difficulty ." </P> <P> Diamond is one of the hardest natural materials on earth; much harder than corundum and silicon carbide . Diamond also has high strength, good wear resistance, and a low friction coefficient . So when used as an abrasive, it has many obvious advantages over many other common abrasives . </P> <P> Diamond can be used to make grinding tools, which have following advantages: </P>
