Diamond Cutting Discs

A wide range of cutting and grinding wheels are avaliable for working either hard, medium or abrasive construction materials.

Cutting discs should only be used for cutting applications, and not for grinding.

As a general rule, wheels are designed to work similar materials. For example, a hard materials blade is designed to cut materials such as engineering brick and reinforced concrete. To enable this, the metal bond or "matrix" which holds the diamond to the body of the tool is relatively soft, as the diamond will blunt quite quickly and it is necessry to keep releasing fresh diamond to the edge in order to keep cutting. An abrasive materials blade however has a bond which is harder, in order to resist premature release of diamonds which are not yet worn out due to the softer nature of the material it is cutting. If a hard blade is used in a soft material the matrix will wear out before the hard bond releases new cutting edges, and it will become blunt. However in this case, the blade can be resharpened by running it in an abrasive material (such as insulation block) for a short period.
