    Vacuum Sanders

    Pair these discs with a vacuum sander to keep your workspace clean. Dust is drawn away through the holes instead of floating into the air or building up on the abrasive. The hook-and-loop mount lets you switch grits without scrapping the disc, unlike adhesive-backed discs. Choose the hole configuration that matches your backup pad and vacuum sander.
    Plastic Abrasive Backing—Tear resistant and the best choice for wet sanding.
    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.
    Silicon Carbide Abrasive—Super sharp to cut quickly under light pressure. Silicon carbide is hard but brittle, so it tends to wear out sooner than other abrasives.
    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

    Image of Product. Front orientation. Sanding Discs. 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.
    Plastic Abrasive Backing—Tear resistant and the best choice for wet sanding.
    Aluminum Oxide Abrasive—The most versatile and affordable abrasive we offer. Aluminum oxide is the go-to choice for general purpose sanding.
