Description

Norton® BlueFire® Coated Abrasive Disc, Large Diameter PSA, Series: R821P, 20 in Disc Dia, 36 Grit, Extra Coarse Grade, Zirconia Alumina Abrasive, Cloth Backing, Y-Weight Backing Weight

Make your first pass over metal or wooden surfaces with this BlueFire® R821P coarse grit large diameter cloth 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 cloth 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.
