Long-Life Arbor-Mount Flap Sanding Discs


	Flat

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.

Threaded Arbor Hole—These discs don’t need a nut to secure, so they're quicker to change out than unthreaded arbors.

Flat Disc—The standard shape.

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.

Nylon Mesh Arbor-Mount Sanding Discs for Stainless Steel and Hard Metals


A	B

C	Flat

Create a consistent finish on stainless steel and other hard metal surfaces before 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.

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.

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

Style A—Sand your workpiece using the face of the disc. Coarse and medium discs require a backup pad (sold separately).

Styles B and C—These discs have a reinforced arbor hole for extra support. You can use both their face and edge to sand workpieces. They don’t require a backup pad.

Threaded Arbor Hole—These discs don’t need a nut to secure, so they're quicker to change out than unthreaded arbors.

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.

Arbor-Mount Flap Sanding Discs for Corners on Stainless Steel and Hard Metals


		Angled

With angled flaps and a tough abrasive, these discs fit inside corners to remove material from hard metals. Their overlapping flaps expose new grit as you work for steady material removal and even finishes. Mount discs onto your tool’s arbor.

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

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

Threaded Arbor Hole—These discs don’t need a nut to secure, so they're quicker to change out than unthreaded arbors.

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.

Nylon Mesh Arbor-Mount Flap Sanding Discs


	Flat

Nylon mesh flaps compensate for uneven pressure to create a consistent finish. Also known as non-woven or surface-conditioning discs, these resist clogging and are often used to prepare surfaces for painting and coating. As the top layer of abrasive wears away, a new layer is exposed, so they last longer than discs without flaps. They fit over your tool’s arbor for the most stable mounting.

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

Threaded Arbor Hole—These discs don’t need a nut to secure, so they're quicker to change out than unthreaded arbors.

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 (Threaded Arbor Hole)	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.

Threaded Arbor Hole—These discs don’t need a nut to secure, so they're quicker to change out than unthreaded arbors.

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.

Trimmable Arbor-Mount Flap Sanding Discs


	Flat

Use every inch of these sanding discs. The soft plastic backing plate can be trimmed as the flaps wear down, so you won't have to replace the disc until all the abrasive is gone. To sand contoured and irregular surfaces, adjust how much the flaps overhang the backing plate. Discs mount onto your tool’s arbor.

Quick-Change Flap Sanding Discs for Corners on Stainless Steel and Hard Metals

Image of Specification. Front orientation. Contains Border. TR. Flap Discs.

Flat

Angled-edge flaps reach farther into corners than discs with standard flaps. These discs have sharp, durable abrasive that cuts through stainless steel, nickel, and other hard metals. The flaps overlap for consistent material removal and even finishes. As the top layer of abrasive wears away, a new layer is exposed, so these last longer than discs without flaps. The connector on the back lets you swap out discs in seconds. Choose the connection style that matches your tool or backup pad.
