Cemented carbide: It is a powder of micron-order refractory high-hardness metal carbides, which is made by using cobalt, molybdenum, nickel, etc. as binders and firing at high temperature and pressure. The content of high-temperature carbide in cemented carbide exceeds that of high-speed steel, with high hardness (HRC75-80) and good wear resistance. The red hardness of cemented carbide can reach 800-1000 degrees. The cutting speed of cemented carbide is 4-7 times higher than that of high-speed steel. High cutting efficiency. The disadvantages are low bending strength, poor impact toughness, high brittleness, low impact resistance and low vibration resistance.

High-speed steel: It is high-carbon and high-alloy steel. According to chemical composition, it can be divided into tungsten series and molybdenum series steel, and according to cutting performance, it can be divided into ordinary high-speed steel and high-performance high-speed steel. High-speed steel must be strengthened by heat treatment. In the quenched state, the iron, chromium, part of tungsten and carbon in the high-speed steel form extremely hard carbides, which can improve the wear resistance of the steel (hardness can reach HRC64-68). The other part of tungsten dissolves in the matrix and increases the red hardness of the steel. The red hardness of high-speed steel can reach 650 degrees. High-speed steel has good strength and toughness. After sharpening, the cutting edge is sharp and the quality is stable. It is generally used to manufacture small, complex-shaped tools.
