8" CLOTH BACKED ALUMINUM OXIDE PSA SANDING DISCS - 10 PACK
Benchmark Abrasives 8" cloth backed aluminum oxide PSA sanding discs are built for tougher sanding applications where a stronger backing and dependable cut matter. Premium aluminum oxide grain handles metalworking, weld blending, deburring, paint and primer removal, wood sanding, fiberglass, plastics, and other common materials, while the X-weight polycotton cloth backing provides greater tear resistance and durability than conventional paper-backed discs.
The pressure-sensitive adhesive backing allows fast peel-and-stick mounting to compatible 8" PSA backing surfaces, while the open-coat construction helps reduce material buildup during sanding. Made in the USA, these discs are a strong choice for users who need a durable PSA abrasive for heavier-duty sanding, fabrication, and finishing work.

Machine Compatibility
Designed for 8" sanding machines equipped with a compatible PSA backing surface, including:
- Stationary disc sanders
- Bench disc sanders
- Belt/disc combination sanders
- Platen disc sanders
- Rotary disc sanders
- Grizzly® H8192 and other 8" sanding machines using a PSA-compatible platen or backing surface
The X-weight cloth backing is especially well suited to applications where the abrasive sees higher pressure, edge contact, or mechanical stress than a typical paper-backed sanding disc.

Why Choose a Cloth Backed PSA Disc?
Cloth backing gives the disc more strength and tear resistance than conventional paper-backed abrasives. That makes it a better fit for harder sanding, metalworking, edge contact, deburring, and other applications where a paper disc may wear or tear too quickly.
The PSA attachment keeps the setup simple: peel the liner, press the disc onto the backing surface, and start sanding.
Tips for Better Sanding Performance
- Apply the disc to a clean, dry PSA backing surface.
- Center the disc before pressing it firmly into place.
- Use moderate pressure and let the abrasive do the cutting.
- Keep the workpiece moving against the disc to avoid localized heat buildup.
- Replace the disc when cutting performance drops or the abrasive becomes excessively loaded.
- Do not use wet; these discs are intended for dry sanding only.

Built for Tougher 8" Sanding Applications
When a standard paper-backed PSA disc is not durable enough, Benchmark Abrasives Cloth Backed PSA Discs provide the extra strength needed for demanding sanding and finishing. The X-weight polycotton backing holds up to harder use, while premium aluminum oxide delivers the dependable cut needed for fabrication, metalworking, woodworking, maintenance, and general shop applications.
For users who need a tougher 8" adhesive-backed abrasive for stationary or bench-mounted sanding equipment, this 10-pack offers a practical step up in durability.
Frequently Asked Questions
These discs use aluminum oxide on a much stronger X-weight polycotton cloth backing, making them better suited to tougher sanding, edge work, weld blending, deburring, and applications where additional tear resistance is useful.
