FLAT TOP CUSHION PADS
Mount these Cushion Pads onto your FLAT TOP DISCS for a smoother grind and more gentle polish. Recommended for use under fine grade abrasives starting from 220 Grit and finer. The additional "give" provides great shock-absorption to your abrasives and allows to work on the contours of rounded and domed workpieces more progressively.
Simply stick them onto the Flat Top Discs before applying an Abrasive. They come in the 3M Bumpon™ flexibility level and only in 4" Diameter, matching the 4" Flat Top Discs.
