A PSA disc is perfect for cleaning and polishing as it creates a smooth surface. PSA Discs are high-quality sanding discs that are designed with PSA (pressure-sensitive adhesive) backing for easy, secure attachment. The discs feature an anti-clog zinc stearate coating to resist dust build-up and a hole-free design to reduce tearing. These PSA Discs offer sharp, efficient, and uniform cutting for sanding jobs that require tear-resistant material and durability. They are extremely effective, responsive, and last longer under high heat and high stress. It is self-adhesive backing that easily attaches to various power tools such as orbital sanders, rotary sanders, disc sanders, and belt disc sanders.
