About Sanding Abrasives

Adhesive-Back Sanding Discs

Press onto a compatible sanding tool or backup pad (sold separately); peel off to remove. Also known as PSA discs. To maintain strong adhesion, clean the pad surface with mild alcohol before applying. Do not use aggressive cleaning solvents such as MEK or acetone, which can damage the adhesive.

Long-Life Adhesive-Back Sanding Discs

Coated with zirconia alumina to stay sharper longer. The abrasive grit continually fractures to produce new, sharp cutting edges. This abrasive is great for aggressively removing material from steel and wood, and it lasts longer than aluminum oxide. Press onto a compatible sanding tool or backup pad (sold separately); peel off to remove. Also known as PSA discs. To maintain strong adhesion, clean the pad surface with mild alcohol before applying. Do not use aggressive cleaning solvents such as MEK or acetone, which can damage the adhesive.

Clog-Resistant Adhesive-Back Sanding Discs

A coating prevents dust and debris from building up on the abrasive surface. Press these discs onto a compatible sanding tool or backup pad (sold separately); peel off to remove. Also known as PSA discs. To maintain strong adhesion, clean the pad surface with mild alcohol before applying. Do not use aggressive cleaning solvents such as MEK or acetone, which can damage the adhesive.

Adhesive-Back Sanding Discs for Masonry, Ceramics, and Composites

Coated with diamond grit, use these discs for sanding hard nonmetals. Diamond's exceptional hardness makes it the best choice for sanding masonry, ceramics, and composites. It lasts longer than silicon carbide and has excellent heat dissipation, preventing material buildup. These discs have a pattern of widely spaced abrasive grains that prevents dust and debris from building up on the abrasive surface.

Nylon Mesh Cushioned Hook and Loop Sanding Discs

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. Quickly attach, remove, and reuse these discs with a compatible sanding tool or backup pad (sold separately).

Coarse grade is for light deburring and removing heavy rust and surface imperfections.

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

Very fine grade is for polishing and final finishing.

Nylon Mesh Cushioned Arbor-Mount Sanding Discs

The abrasive-embedded mesh construction gives you more control over sanding pressure, creating finer and more consistent finishes. Fit these discs over your tool’s arbor. They don’t require a backup pad.

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 polishing and final finishing.
