Grade

The relative holding power of the bond which holds abrasive grains within a wheel-degree of "hardness" of strength is indicated softer grades in low alphabet and harder grades in high alphabet.


Abrasive grains with light bond coating and weak connecting bond posts as in a relatively soft grade wheel. (Bright areas are the pores, required for chip clearance).	Abrasive grains of same size but with heavier bond coating and thicker, stronger bond posts as in a hard grade wheel.
