A grinding wheel is designated coarse, medium, or fine according to the size of the individual abrasive grains making up the wheel. BONDING MATERIAL Bond The abrasive particles in a grinding wheel are held in place by the bonding agent. The percentage of bond in the wheel

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

This ensures a smooth sanding. Choose quality products - so you avoid irregularities in the paper that can damage the substrate. How closely a product is coated - i.e. how many sand grains there are per m2 varies. Typically 50 to 75% of the surface is covered with grain. The coarse grit sizes are usually scattered more open than the finer.
