Adhesive-Back Sanding Discs

Press these discs onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.

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.

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.

Mount these discs directly to your tool’s arbor for the most stable, controlled sanding. They require a backup pad.

Fiber Abrasive Backing—The stiff backing lets you apply maximum force on flat or angled surfaces without the disc collapsing or tearing.

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.

Quick-Change Sanding Discs for Soft Metals, Plastic, and Rubber


	TR

Prevent clogging and smearing when sanding soft materials. The abrasive won’t trap particles, so these discs reduce heat to stay sharp. Twist or snap the connector on the back to swap out discs in seconds. Choose the connection style that matches your tool or backup pad.

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

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.

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.

See-Through Arbor-Mount Sanding Discs

Flat

Check on your surface as you work to avoid over-sanding expensive or delicate workpieces. These discs have three holes you can see through and one for mounting onto your tool's arbor. They require a compatible see-through backup pad (sold separately).

Fiber Abrasive Backing—The stiff backing lets you apply maximum force on flat or angled surfaces without the disc collapsing or tearing.

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

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.

Quick-Change Sanding Disc Assortments


	TP

Tackle a range of sanding jobs. These assortments include a variety of grits for everything from heavy material removal to finishing. The connector on the back lets discs swap out in seconds, so you can get right back to work. Choose the connection style that matches your tool or backup pad.

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

TP Style Quick-Change Connector—These assortments are larger than TR style, with two abrasive materials and the compatible backup pads.

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.

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


	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.

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.

Adhesive-Back Sanding Discs for Stainless Steel and Hard Metals

The abrasive on these discs is sharp and durable enough to cut hard metals without dulling quickly. Press discs onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.

Plastic Abrasive Backing—Tear resistant and the best choice for wet sanding.

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

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.
