Product Specification

12" CLOTH BACKED ZIRCONIA PSA SANDING DISCS - 10 PACK

Benchmark Abrasives 12" 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 12" 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.

Quantity: 10 discs

  • Grizzly® G7297 and other 12" sanding machines using a PSA-compatible platen or backing surface

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 moving against the disc 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.
  • Use appropriate eye, hearing, respiratory, and hand protection.

Built for Aggressive 12" Sanding Applications

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 using larger stationary sanding equipment, these 12" zirconia discs deliver the cutting power and durability needed for heavy stock removal, weld cleanup, and demanding surface preparation.

Customer Reviews (4.8 / 5 · 5 reviews)

Avery N. ★★★★★

I was surprised these 12-inch discs actually stayed put on my orbital sander without peeling off; the cloth backing makes a noticeable difference in durability over paper ones.

Joseph ★★★★★

Finally got these for some heavy stock removal, and the zirconia grit stays sharp way longer than standard discs I've used before. The hook-and-loop PSA backing held firm through an entire session without any peeling.

Edward U. ★★★★★

The cloth backing on these discs gives them a nice flexibility that really hugs curved surfaces without tearing. I’ve been using them on my 12-inch sander for some heavy stock removal, and the zirconia grit holds up well past what I expected.
