Long-Life Arbor-Mount Flap Sanding Discs

Flat

Angled

With more abrasive than standard flap sanding discs, these last 30-40% longer. Their overlapping flaps reveal new grit as you work for steady material removal and even finishes. Fit discs fit over your tool’s arbor for the most stable mounting.

Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

Aluminum Oxide Abrasive—The most versatile and affordable abrasive we offer. Aluminum oxide is the go-to choice for general purpose sanding.

Zirconia Alumina Abrasive—A step up from aluminum oxide. Zirconia alumina's tough grains remove material faster and last longer but require heavy pressure to cut properly.

Flat Disc—The standard shape.

Angled Disc—Make better contact on irregular surfaces than flat discs, so they're good for sanding bumps, contours, and edges.

Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.

Arbor-Mount Flap Sanding Discs for Soft Metals, Plastic, and Rubber


Flat	Angled

Coated abrasive flaps resist buildup from soft metals and nonmetals that would clog and prematurely wear other discs. As the top layer of abrasive wears away, a new layer is exposed so these last longer than discs without flaps. Mount them onto your tool’s arbor.

Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

Ceramic Alumina/Zirconia Alumina Blend Abrasive—Combine the fast cutting of ceramic alumina with the toughness of zirconia alumina under heavy pressure.

Fast-Cutting Nylon Mesh Arbor-Mount Sanding Discs


Precision-Shaped Ceramic Alumina	Flat

Remove material quickly without sacrificing a consistent finish. These discs have precision-shaped abrasive that cuts easily through hard metals and reduces heat to prevent wear. The grains continually fracture to expose fresh cutting edges while keeping their engineered points and angle. Also known as non-woven or surface-conditioning discs, their flexible mesh backing resists clogging and adapts to uneven sanding pressure. They're good for everything from heavy rust removal to paint prep. Discs mount onto your tool’s arbor and require a backup pad.

Ceramic Alumina Abrasive—The sharp edges cut quickly for efficient material removal.

Flat Disc—The standard shape.

Nylon Mesh Grade—Use coarser grade discs for heavy cleaning, stripping, and deburring. Finer grades remove material more slowly, so they're best for gentle cleaning, blending, and finishing.

Nylon Mesh Arbor-Mount Sanding Discs


Silicon Carbide (Unthreaded Arbor Hole)	Flat

Achieve a more consistent finish to prepare surfaces for painting and coating. With a nylon mesh backing instead of cloth or paper, these discs resist clogging and flex to compensate for uneven sanding pressure. They’re also known as non-woven or surface-conditioning discs. Mount directly onto your tool’s arbor for stable, controlled sanding without a backup pad.

Silicon Carbide Abrasive—Super sharp to cut quickly under light pressure. Silicon carbide is hard but brittle, so it tends to wear out sooner than other abrasives.

Flat Disc—The standard shape.

Nylon Mesh Grade—Use coarser grade discs for heavy cleaning, stripping, and deburring. Finer grades remove material more slowly, so they're best for gentle cleaning, blending, and finishing.
