This is a hard question to answer in a short space. While the markings mean the wheels should perform the same, differences in factory equipment and marking systems may make one product behave differently than another. They should be close, but the only true way to match a product is to have a wheel analysis done by the factory. We do this for no charge and it is recommended for larger purchases to eliminate testing. Note that even when an analysis is done, it is no guarantee the wheels will perform exactly the same.
What is the specification?
A typical grinding wheel specification consists of the grit type, the grit size, the hardness, the structure and the bond. A typical grinding wheel specification would be A60-I10-VS. ‘A’ is the grit type (aluminum oxide), ’60’ is the
