3M Disc Pad Holders have a center hole with internal threads?choose the thread size that matches the external thread size of your right angle grinder. T-shaped hooks securely hold a surface conditioning disc and provide quick and easy disc attachment, removal, and re-attachment. The hook-and-loop feature enables the disc to be used and re-used for the extent of the abrasive life. Discs are sold separately.
Our Scotch-Brite surface conditioning discs and light grinding/blending products (sold separately) deburr, clean, blend, and finish a wide variety of materials. Using surface conditioning products with a 3M disc pad holder generates finishes suitable for paint.
