M. GRINDING WHEEL GRADE. The grade of a grinding wheel refers to its hardness, i.e. how securely the abrasive grains are held by the binder. It does not, therefore, depend on the hardness of the abrasive used in the wheel. The grade of a grinding wheel is determined primarily by the quantity of binder used in the wheel.
