Understanding Grinding Wheel Hardness

Softer or weaker bonds means the grains let go with considerably less force and surface friction which make them perfect for larger areas and preferred for grinding harder materials. A harder bond is best for softer materials. A typical weak bond for steel would be in the 'F, G or H' range. A medium hardness would be in the 'J, K or N' range.
