PSA (Sticky-back) Sanding Discs

PSA (Pressure Sensitive Adhesive) Sanding Discs offer a quick and secure attachment to backup pads, eliminating the need for complicated alignment. Their flat, edge-to-edge bond provides a more stable sanding surface than hook-and-loop systems, which reduces disc "wobble" and results in a more uniform finish on hard surfaces. Particularly popular in coarse to medium grits for applications where heavier stock removal is required.
