Frequently asked questions
Will these fit my sander? These are made for 17-hole backup pads/machines so the holes align for extraction. If your pad has a different hole count, choose the 6-hole (630), 8-hole (640) or 9-hole (690) Red Line disc instead.
Do I need a vacuum sander? For dust-free results, yes — pair with a vacuum-ready sander and extractor.
Red Line vs White Line? Red Line is the premium, longest-life, highest-cut line; White Line is the everyday line.
