Understanding Grinding Wheel Hardness. The amount of abrasive bond in the grinding wheel determines its grade or hardness. Hardness is dependent on the grit type, the material being ground, the amount of stock removed, and a number of other factors. Hardness is rated from A-Z, with “A” being the weakest bond and “Z” being the strongest.
