Made using the hardest material in the world, Bona Diamond Abrasives maintain their sanding performance up to 15 times longer. In tests, both screen and multihole sanding discs lose their sanding capacity after a short period, while Bona Diamond Abrasives maintain an even sanding performance, even after 100 m2 of sanding.
While sanding on bare wood, Bona Diamond Abrasives maintain their original sharpness and sanding capacity for well over 100 m2, or after 80 mintes of sanding. Competing screen and multihole discs begin to lose their sharpness after 15 m2 of sanding, in just 12 minutes.
