The diamond is the hardest tool material and can run at cutting speeds about 50 times that of high speed steel tool.

the ceramic tools can be used at cutting speeds 40 times that of high speed steel tools.

The cemented carbide tools can be used at cutting speeds 10 times that of high speed steel tools.

The ceramic tools can withstand temperature up to 600 degree centigrade only.
