3M™ Clean Sanding Interface Disc Pad, 28324, grey, 3 in x 4 in x 1/2 in (76.2 mm x 101.6 mm x 12.7 mm), 33 holes

3M™ Clean Sanding Interface Disc Pad is constructed of 1/2 in (12.7 mm) medium-density foam with a clean sanding hole pattern to add conformability to a 3M™ Hookit™ Clean Sanding Backup Pad (sold separately). When used with a 3M™ Clean Sanding Backup Pad, this disc increases conformability, allowing the technician to follow contours and get in closer to most edges, while maximizing dust extraction.

3M™ Clean Sanding Interface Disc Pad contains a series of uniquely designed holes and channels which allow dust to be pulled through the holes and away from the sanding surface. This improves the work environment and prolongs disc life. 3M's clean sanding dust-management system evacuates dust from the work surface better than 5- or 6-hole products, dramatically increasing disc life and maximizing cut-rate. Optimized with a self-generated vacuum sanding tool fitted with a 3M™ Clean Sanding Filter Bag (sold separately), 3M™ Clean Sanding Products allow the vacuum to suction dust from the air and off of the workpiece. This reduces loading of the disc and adds life to the abrasive. Additionally, reducing dust in the air improves working condition
