A flap disc in an incredibly versatile abrasive disc that is long lasting, affordable, and available in multiple styles to fit different tools. Abrasive flaps are installed, overlapping one another, to a center hub. As the flap disc is used to grind a surface down, the flaps will tear away to expose fresh flaps of abrasive material. This allows for a cooler cut and less time wasted swapping out discs that would have become dull or clogged with use.
