Flap Discs for Sale

Over the last decade, flap discs have been the fastest growing abrasives category in metal fabrication. Many find them a more efficient process because they offer fast stock removal and provide grinding, blending and finishing with one product. Compared to grinding discs, they are lighter weight, easier-to-control and require less downtime for product changes.

We offer a vast selection of flap discs from the USA and Germany, including zirconia and ceramic flap discs, flap discs for aluminum, and genuine 3M™ Cubitron™ flap discs. Our quality-made flap discs are designed with versatility and stability during each operation. To efficiently get the job done in one operation, browse our collection of abrasive flap discs for your next project.
