I think that's what he has. 3m is the best thing going as far as Velcro goes I believe. You might not find a quality one unless it's that brand. When I was on the tool truck I sold a lot of PSA sandpaper. "sticky pads" But that was sandpaper and not "sander discs". What grit are you using. Anything coarser than 80 grit and you should be using a high speed grinder and not a DA. These discs have a hole in the middle and a big nut to attach them to a fiber backing disc.
