|
| SDR80 |
|
| SDR80 contains completely optimized crystals with good transparence, higher purity and impact strength. It is suitable for higher thermal impact requirements on top cutting, drilling and grinding tools. |
 |
|
|
| SDR60 |
|
SDR60 high grade contains complete crystal shape, good transparence and low impurity. It is suitable for wider range of sawing conditions which request high impact ability.

|
| SDR30 |
|
| SDR30 comparatively contains more regular crystal shape, sharp edges with mid-toughness and medium thermal stability. It is widely used for general quality blades in moderate applications. |
 |
|
|
| SDR20 |
|
| SDR20 belong to economy and low grade diamond with irregular crystal shape, suitable for grinding tools that with low load. |
 |
|
|
| SDR15 |
|
| SDR15 economy grade, irregular crystal shape, rough surface, lower strength, which crystals with a broader distribution of shape and strength. It is recommended for low load work. |
