Used for polishing and touching up molds, dies and metal parts. Less aggressive than finishing stones, GMX sticks produce a surprisingly smooth surface.

GMX is made of a long lasting Aluminum Oxide grit in a unique composite of laminated cotton fiber in a rubber bond. GMX cuts and smooths in one operation leaving a smooth even surface finish.

Available in 4″ long square sticks, and in 4″ and 6″ long round sticks.

• 80 grit is ideal for deburring
