Remark: Based on different raw materials and production processes, CRC, CRJ, GMDP diamond wheel grits are available to meet different needs.

Grades Desription 

GMD650 is a polyhedron diamond with regular hexahedron and octahedron crystal shape. High transparency, low impurity, high toughness and thermal stability. It is suitable for environment where the impact load is large and the product is required to maintain a good shape.

GMD450 is a medium strength crystal with a complete shape, high thermal stability, high toughness and uniform crystal shape distribution. It usually used in the glass industry, can effectively prolong the service life of tools.

GMD210 consists of a multi angled crystal with good sharpness, relatively low impact toughness, a lot of sharp edges. Its fragility is the best in the GMD series. It is suitable for the lower load grinding and large area contact processing applications.

Available sizes is from 80/100 to 500/600, it can also be tailor-made for customers to meet their individual needs.

Remark: Special size range could be customer-oriented.

Coating Brief

Coating generally improves the wettability of the diamond, making the retention between the diamond and the bonding agent stronger. At the same time, the coating can also protect the diamond from the corrosion of materials such as metal powder in the formulation, thereby prolong the life of the tool.

The coating and coating level is as follows:


Note:  The coating and coating level can be customized according to customers' requirement.
