As far as processing non-ferrous materials is concerned, the durability of diamond tools is relatively high. But usually diamond can't be used to cut iron-based materials such as steel and cast iron.

Cubic boron nitride (CBN) and ceramics are more wear-resistant when processing iron-based materials. CBN is suitable for processing high-hardness materials (such as >: 45HRC). Different CBN content is suitable for different conditions, please note.

Ceramic materials are more durable through whisker toughening.

As far as cemented carbide and high-speed steel are concerned, coated tools are generally more wear-resistant, of course, without the wrong coating and proper use. Different coatings have different best choices for different processing materials and different cutting conditions. And the coating with the same chemical structure will have very different results if the process is different.

Generally speaking, the smaller the particle size, the better the durability, but the more expensive it is.

High speed steel contains more than 5% cobalt and 1% aluminum in cost, so the durability of powder metallurgy is better in smelting method.

These materials are usually more wear-resistant at the top.
