1. Extremely high hardness and wear resistance: diamond is the hardest substance found in nature, and granite cutting discs have extremely high hardness and wear resistance.
2. The cutting edge is very sharp: The cutting edge of diamond tools can be sharpened very sharply.
3. Good thermal conductivity: diamond has high thermal conductivity and thermal diffusivity, cutting heat is easy to dissipate, and the temperature of the cutting part of the saw blade is low.
4. Lower coefficient of thermal expansion: The coefficient of thermal expansion of diamond is several times smaller than that of cemented carbide, and the change in tool size caused by cutting heat is small.
