These discs have a harder abrasive than standard flap sanding discs.

Replace your sanding discs less often—the backing plate on these discs can be trimmed off as the abrasive flaps wear down, allowing you to use more of the disc.

The flaps wrap around the outer edge of these discs to sand welds at right angles.

With more flaps than standard discs, these last 30-40% longer.

A coating prevents dust and debris from building up on the abrasive surface.

The zirconia alumina grit on these discs continually fractures to produce new, sharp cutting edges that aggressively remove material from steel and wood.

Set at an angle and widely spaced, the flaps reach into corners.
