3M disc pad holders allow you to quickly and easily change Scotch-Brite abrasive discs during multi-step projects. Available in a range of sizes, foam densities and attachment options, so you can find the perfect holders for your grinding and sanding projects. 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 reattachment. 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.
