Types of Sanding Discs

Resin Fiber Discs

Resin fiber discs are an affordable abrasive disc made with a heavy-duty fiber backing. The abrasive grains are embedded in the resin bonding agent which coats the fiber back. Please note, a compatible sized backing pad (sold separately) is required to attach the fiber disc to your grinder.

Flap Discs

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.
