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.

Materials & Applications
Suitable for sanding and finishing:
Steel
Stainless steel
Cast iron
Titanium
Nickel alloys
Wrought iron
Aluminum and other non-ferrous metals
Copper and brass
Wood
Paint and primer
Fiberglass
Plastics
Hard rubber
Best For: Metal finishing, weld blending, deburring, surface preparation, paint and primer removal, edge sanding, wood sanding, and applications where a stronger cloth-backed disc is preferred over paper.
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.
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
Gold PSA discs use aluminum oxide on a C-weight paper backing and are designed for broad general-purpose sanding.
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.
They are designed for 8" stationary disc sanders, bench disc sanders, belt/disc combination sanders, platen disc sanders, rotary disc sanders, and other machines with a compatible 8" PSA backing surface.
For handheld orbital sanding, choose a non-vacuum setup. A stationary disc sander can still collect dust through a hood or port beside the disc—the dust does not need to pass through the abrasive. Follow the machine’s material and dust-collection guidance.
Yes. Each disc has a release liner that protects the pressure-sensitive adhesive until you are ready to mount it.
No. Both use aluminum oxide abrasive, but the backing construction is different. Gold PSA discs use C-weight paper, while these use X-weight polycotton cloth for greater strength and tear resistance.
The abrasive grains are spaced to leave more room for sanding debris, which helps reduce loading on materials such as paint, wood, plastic, and filler.
Yes. They are especially well suited to ferrous and non-ferrous metals, including steel, stainless steel, cast iron, aluminum, copper, brass, titanium, and nickel alloys.
No. These cloth-backed PSA discs are intended for dry sanding only.
For heavier weld blending, start with 40 or 60 grit. Use 80 or 120 grit afterward when additional scratch refinement is needed.
Replace it when cutting performance noticeably slows, the abrasive becomes excessively loaded, the cloth backing becomes damaged, or the adhesive no longer holds securely.
