Adhesive-Back Sanding Discs
 |
Press these discs onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.
Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.
Aluminum Oxide Abrasive—The most versatile and affordable abrasive we offer. Aluminum oxide is the go-to choice for general purpose sanding.
Zirconia Alumina Abrasive—A step up from aluminum oxide. Zirconia alumina's tough grains remove material faster and last longer but require heavy pressure to cut properly.
Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.

Clog-Resistant Adhesive-Back Sanding Discs
 |
Spend more time sanding and less time replacing clogged discs. A slick coating prevents dust and debris buildup on the abrasive surface. Press these discs onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.
