Are diamond-coated tools suitable for machining ductile iron?

Suitable. When cutting ductile iron, diamond-coated tools can reduce tool wear, extend the service life of the tool, and improve processing efficiency and product quality, so they are suitable for processing ductile iron. Diamond cutting tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals.
