3M 7100278691 | 89925 Xtract 5" Diameter x 5/16"-24 EXT Thread x 11/16" Thickness Back-up Pad

3M Xtract Back-up Pad holds net discs and discs with a clean sanding hole pattern (sold separately), helping enable up to 97% dust extraction. It has a tapered edge which provides conformability and edge flexibility, ideal for feather-edging or blending a painted area to match the rest of the workpiece.

Features:

• Multi-hole pattern maximizes dust extraction with a central or self-generated vacuum system (sold separately)
• Medium density foam provides some conformability for surface sanding
• Tapered edge performs well when flexibility is needed for feather-edging or blending a painted area
• External threads are compatible with orbital or random orbital sanders with similar internal threads (1/4-20 for 3" random orbital sander or 5/16-24 for 5" and 6" random orbital sanders)
• 3M Hookit hook-and-loop attachment provides excellent backing support and easy reuse, optimizing disc life
