Designed for use with random orbital sanders and right-angle grinders, the A290 medium grit paper PSA disc offers outstanding value and reliable performance on blending, sanding and paint removal projects. The P-graded aluminum oxide abrasive cuts fast and ensures a consistent finish while delivering excellent longevity. To reduce loading, the disc features a water-based stearate, no-fil coating and open coat, while the flexible C-weight latex-saturated backing is reinforced with fiber for added tear resistance. To enable fast disc changes, the disc comes equipped with a pressure sensitive adhesive.
