Milling Inserts
Application
Milling inserts act as precision cutting teeth for machine tools to machine various metals. These indexable inserts cut, slot and profile workpieces via high-speed rotating milling cutter bodies. Modern inserts adopt cemented carbide substrates with multi-layer nano coatings, delivering sharp cutting performance and long wear resistance simultaneously.
