About Sanding Abrasives

Long-Life Flap Sanding Discs

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

Flap Sanding Discs

Overlapping abrasive flaps bonded to a backing plate provide consistent material removal and even finishes.

Long-Life Fast-Cutting Flap Sanding Discs

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

Fast-Cutting Flap Sanding Discs

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

Nylon Mesh Cushioned Flap Sanding Discs

The abrasive-embedded mesh construction gives you more control over sanding pressure, creating more consistent finishes.

Aggressive-Removal Flap Sanding Discs

A heavy duty backing plate provides more support than standard discs for heavy material removal.

Trimmable Flap Sanding Discs

The backing plate on these discs can be sheared away as the abrasive flaps wear down, allowing you to use more of the disc rather than replacing with a new one.

Cool-Sanding Flap Sanding Discs

The flaps alternate between an abrasive to remove material and a lubricant that minimizes heat to reduce discoloration of the work surface.

Flap Sanding Discs for Corners

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

Long-Life Flap Sanding Discs for Corners

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

Flap Sanding Discs for Right-Angle Welds

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