Benchmark Abrasives 6" cloth backed zirconia PSA sanding discs are built for aggressive sanding and high stock removal where durability and cutting speed matter. Premium zirconia alumina grain self-sharpens as it wears, helping maintain a fast cut under higher heat and pressure, while the X-weight polycotton cloth backing provides the strength and tear resistance needed for demanding sanding applications.
The pressure-sensitive adhesive backing allows quick peel-and-stick mounting to compatible 6" PSA backing surfaces, while the open-coat construction helps reduce loading during use. Made in the USA, these discs are an excellent choice for metal fabrication, weld blending, deburring, heavy surface preparation, and other jobs where aluminum oxide may not provide enough cutting power or life.

Wood
Best For: Heavy material removal, weld blending, deburring, rust and scale removal, aggressive surface preparation, shaping, paint removal, and demanding fabrication work.
Machine Compatibility
Designed for use on 6" sanding equipment equipped with a compatible PSA backing surface, including:
Stationary disc sanders
Rotary sanders
Random orbital sanders
Disc sanders
Platen disc sanders
Belt/disc sanders
WEN® 6502T and other 6" sanding machines using a PSA-compatible backing pad or platen
The combination of zirconia grain and X-weight cloth backing makes these discs especially well suited to applications involving higher pressure, harder materials, and aggressive stock removal.
Why Choose Zirconia?
Zirconia alumina is designed for tougher sanding than standard aluminum oxide. As the grain fractures during use, fresh cutting edges are exposed, helping the abrasive continue cutting efficiently instead of simply dulling.
That makes zirconia especially effective for weld work, fabrication, scale removal, deburring, and heavy stock removal where higher pressure and heat are common.
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 firm, even pressure and let the zirconia grain do the cutting.
Keep the workpiece or sander moving to avoid localized heat buildup.
Replace the disc when cutting performance noticeably decreases.
Do not use wet; these discs are intended for dry sanding only.
Benchmark Abrasives cloth backed zirconia PSA discs combine a tough self-sharpening abrasive with a heavy-duty cloth backing for jobs that demand more than a standard paper-backed sanding disc.
For fabricators, welders, metalworkers, and shops that need fast cutting, longer abrasive life, and dependable performance under pressure, zirconia is the stronger choice.
Frequently Asked Questions
Zirconia is tougher and self-sharpening, allowing it to maintain a fast cut under higher heat and pressure. It is typically preferred for aggressive stock removal, weld blending, deburring, and heavy metalworking.
They can be used on 6" stationary disc sanders, rotary sanders, random orbital sanders, platen disc sanders, belt/disc sanders, and other machines with a compatible 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.
For heavier metalworking and aggressive stock removal, usually yes. Zirconia handles heat and pressure better and is designed to keep cutting as the grain wears.
Yes. They can also be used on wood, fiberglass, plastics, and hard rubber, although their biggest advantage is in harder and more demanding sanding applications.
No. These cloth-backed zirconia PSA discs are intended for dry sanding only.
Replace it when cutting performance noticeably slows, the abrasive becomes excessively loaded, the cloth backing becomes damaged, or the adhesive no longer holds securely.
