When you need to achieve a more consistent finish, choose nylon mesh sanding belts over paper- or cloth-backed belts. The mesh flexes to compensate for uneven sanding pressure as you sand. It's embedded with ceramic alumina; its grit continually fractures to produce new, sharp cutting edges. It's sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron without dulling quickly. It sands faster and lasts longer than aluminum oxide but requires more force to abrade properly.

Extra coarse grade is for deburring and removing heavy rust and surface imperfections. It is equivalent to 120 to 150 grit.
