May 01, 2017 The exposed diamond crystals do the grinding work. The metal matrix or bond holds the diamonds in place. Trailing behind each exposed diamond is a “bond tail” which helps to support the diamond. As the blade rotates through the material the exposed surface of the diamonds grind the material being cut into a fine powder
