The term ‘Mesh’ is used to describe the size of an abrasive particle. In some instances, such as with Aluminum Oxide Grit or Silicon Carbide Grit, a single number is used.This does not mean every particle in that product is exactly that size but rather thanmeshsize indicator is approximately the mean or average size of the range of particles in that grade.
