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.
Secure and Easy to Switch
Our hook-and-loop feature makes disc attachment, removal, and re-attachment easy and facilitates use and re-use of the disc for the extent of the abrasive life. Our disc pads have T-shaped hooks of the type most commonly used in hook-and-loop applications. These disc pads grip the loop backings of hook-and-loop discs and provide a finer finish than do adhesive backed discs. Hook-and-loop systems are designed for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris.
Made for Scotch-Brite
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.
