KRD70 is the second premium product in KRD family. The grit consists of blocky cubo-octahedral crystals with high strength and thermal stability. KRD70 is suitable for a wide range of applications in stone and construction industries.

Medium Grades

KRD60 is a quality medium grade product for general purpose applications. Containing a high level of cubo- octahedral crystals, the grit is suitable for sawing and drilling medium hard stones.

KRD50 is a general purpose grit maintaining moderate impact strength and thermal stability. The product is ideal for sawing and drilling medium-to-soft stones.

Economic Grades

KRD40 is slightly friable product. The product still contains a relatively high level of cubo-octahedral crystals. It is recommended for light duty applications where tools life is not the prime consideration.

KRD30 is a moderately friable abrasive with irregular cubo-octahedral crystals. The product is ideal for economic applications such as sawing soft marble and limestone.
