White steel milling cutter Also known as high-speed steel, the hardness is relatively soft, the high-speed steel knife is cheap, and the toughness is good, but the strength is not high, it is easy to let the knife, and the wear resistance and thermal hardness are relatively poor. The thermal hardness of the high-speed steel milling cutter is about 600 degrees. When milling harder materials with white steel, it is easy to burn the knife if the coolant is not in place. This is one of the reasons why the low thermal hardness.

carbide milling cutter
Cemented carbide (tungsten steel) has good thermal hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties. In particular, the high hardness and wear resistance, even at 500 degrees, remain basically unchanged, and still have a high hardness at 1000 degrees.
ceramic milling cutter
Also known as oxidation milling cutter, high hardness, heat resistance up to 1200 degrees, high compressive strength, but the brittleness is too large so the strength is not high, so the amount of cutting can not be too large. Therefore, it is more suitable for final finishing, or other highly wear-resistant non-metallic products.
superhard material milling cutter
Whether it is in the hardness, wear resistance, or heat resistance is excellent, there is enough toughness, its withstand temperature can reach 2000 degrees, because the brittleness is too large and the strength is not high, more suitable for final finishing.
