FLAP DISCS: 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.
