... in.). Optimum grit size varies with different types and sizes of gears. A 280-grit abrasive is used for spiral bevel gears; a finer abrasive (about 400-grit) is more suitable for hypoid gears because the sliding action is greater. As a rule, coarser grit is used for gears having a coarse pitch, and finer grits...
