3M™ Disc Pad Holder enables the use of 3 inch 3M™ Hook and Loop Discs on right angle grinders. It features 3M™ Dual-Lock™ Hooks to securely hold disc to sander and to provide easy attachment and removal. 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.
