How do diamond blades work?
Diamond blades don’t cut, they grind!
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.
After several thousand passes through the material being cut, the exposed diamonds begin to crack and fracture.
The matrix holding the diamond also begins to wear away.
Eventually the diamond completely breaks up and its fragments are swept away with the material that it is grinding.
As the diamond wears and fractures, controlled erosion of the metal bond containing the diamond exposes new sharp diamond points.
This cycle of erosion and exposure continues until all of the diamond and metal bond section of the segment is gone.
Once the cutting section is consumed the blade will no longer grind letting the operator know it is time for a new blade.
