Diamond grinding grains with metallic bonding are used because they offer high thermal conductivity and excellent wear resistance. The metallic bonding allows for efficient heat dissipation during the grinding process, preventing the diamond grains from overheating and becoming dull. This makes them ideal for grinding hard and brittle materials such as ceramics, glass, and composites. Additionally, the metallic bonding provides strong adhesion between the diamond grains and the grinding tool, ensuring long-lasting performance and consistent material removal. **
