Make your first pass over metal or wooden surfaces with this BlueFire R821P coarse grit large diameter PSA disc in your stationary grinder. Its self-sharpening zirconia-alumina abrasive face makes cooler cuts during coarse grit sanding, which helps extend the life of the disc. This large-diameter PSA disc uses a strong resin bond and heavy-duty Y-weight polyester backing to improve grain adhesion and edge-tear resistance. A pressure sensitive adhesive backing lets you easily apply or peel away the disc for quick changes. Use it for deburring, sanding, and blending, or load it on your orbital sander to strip paint.
