702-20 is a 7" x 1-1/2" foam wheel.  It is used with the Model 760 and X400 belt grinders.  The 702-20 has a 5/8" arbor.

Looking for a smooth finish? The foam wheel provides the ultimate smooth finish to your grind.  The foam rubber allows even the joint of the belt to pass without getting a nasty hump. 

Pair this wheel with a micro finishing belt or a Trizact belt and you’ll see a finish that will make you smile.
