Clog-Resistant Arbor-Mount Sanding Discs


Unthreaded Arbor Hole	Flat

Spend more time sanding and less time replacing clogged discs. A coating prevents dust and debris buildup that can wear out the abrasive. These discs fit over your tool’s arbor for the most stable mounting and 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.

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.

Fast-Cutting Arbor-Mount Sanding Discs


Unthreaded Arbor Hole	Precision-Shaped Ceramic Alumina	Flat

Remove material more quickly than other arbor-mount discs. These have precision-shaped abrasive that cuts easily and reduces heat to prevent wear. The grains continually fracture to expose fresh cutting edges while keeping their engineered points and angle. These discs fit over your tool’s arbor for the most stable mounting and 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.

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

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.
