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.
Discs with plastic abrasive backing have a coating that prevents dust and debris from building up on the abrasive surface. They also resist deterioration when used wet.

Cushioned Adhesive-Back Sanding Discs
The cushioned construction gives you more control over sanding pressure, creating finer and more consistent finishes. These discs resist deterioration when used wet. 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.

Adhesive-Back Sanding Discs for Stainless Steel and Hard Metals
The ceramic alumina abrasive on these discs is sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron without dulling quickly. Its grit continually fractures to produce new, sharp cutting edges. It sands faster and lasts longer than aluminum oxide but requires more force to abrade properly. 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.
Discs with paper backing come on a roll.Clog-resistant discs have a slick coating on the abrasive surface that reduces debris from building up and keeps operating temperatures low.

Hook and Loop Vacuum Sanding Discs
Holes allow dust removal when used with a vacuum sander.
A slick coating prevents debris from accumulating on the abrasive surface and keeps operating temperatures low. Quickly attach, remove, and reuse discs with a compatible sanding tool or backup pad (sold separately). Discs with plastic backing resist deterioration when used wet.
Add an optional cushioning pad between the disc and backup pad. It has a foam layer that conforms to bumps and crevices and distributes pressure more evenly as you sand, leaving a finer and more consistent finish.

Add one of these foam pads between your sanding disc and backup pad to create a cushioned layer while sanding. They conform to bumps or crevices and distribute pressure more evenly on your workpiece as you sand, leading to finer and more consistent finishes.
Clog-Free Hook and Loop Vacuum Sanding Discs
The mesh backing allows dust removal when used with a vacuum sander, preventing material build up on the abrasive surface. Quickly attach, remove, and reuse these discs with a compatible sanding tool or backup pad (sold separately). These discs work with any backup pad hole configuration because the mesh backing covers the entire disc.
