When you need to achieve a more consistent finish, choose nylon mesh sanding discs over paper- or cloth-backed discs. The mesh flexes to compensate for uneven sanding pressure as you sand. It's embedded with aluminum oxide, the most common abrasive, which is hard enough to sand steel and wood. Attach these discs to your tool’s arbor. Discs with threaded arbor hole don’t need a nut to secure, enabling quick disc changes.

Overlapping abrasive flaps bonded to a backing plate provide consistent material removal and even finishes. As the top layer of abrasive wears away, a new layer is exposed, so these last longer than discs without flaps. Angled discs remove material on flat surfaces faster than flat discs. You can also use them to contour edges and surfaces. Flat discs blend and finish on surfaces, edges, and even in corners.

Coarse grade is for light deburring, and removal of heavy rust and surface imperfections.

Medium grade is for moderate blending, cleaning, light deburring, and general finishing.

Fine grade is for light cleaning and finishing.

Very fine grade is for light scratch removal, finishing, and polishing.
