Quick-Change Sanding Discs for Masonry, Ceramics, and Composites
 |  |
TR |
The hardest of all abrasives, diamond is the best choice for extremely hard materials. These discs cut quickly and wear slowly when sanding masonry, ceramics, and composites. Their unique abrasive pattern prevents material buildup and leaves a consistent finish. The connector on the back lets you swap out discs in seconds. Choose the connection style that matches your tool or backup pad.
Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

Adhesive-Back Sanding Discs for Masonry, Ceramics, and Composites
 |
The hardest of all abrasives, diamond is the best choice for extremely hard materials. These discs cut quickly and wear slowly when sanding masonry, ceramics, and composites. Press them 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.
