Product Specification

8" CLOTH BACKED ZIRCONIA PSA SANDING DISCS - 10 PACK

Benchmark Abrasives 8" 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 8" 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

Machine Compatibility

Designed for 8" sanding machines equipped with a compatible PSA backing surface, including:

  • Stationary disc sanders

  • Rotary disc sanders
  • Grizzly® H8192 and other 8" 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 8" 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 8" zirconia discs deliver the cutting power and durability needed for heavy stock removal, weld cleanup, and demanding surface preparation.

Customer Reviews (4.4 / 5 · 5 reviews)

Hannah ★★★★★

Finally found discs that actually stay on my random orbital sander during heavy use. The zirconia cuts through paint and rust way faster than the aluminum oxide ones I was using before.

Joseph V. ★★★★★

These discs are holding up really well on my 8" sander so far. The cloth backing makes them feel a lot more durable than the paper ones I've used, and they're not tearing at the edges. Definitely grabbing another 10-pack when I run through these.

Jason ★★★★☆

The cloth backing makes these discs hold up well during heavy use, and the zirconia cuts through paint quickly. Only wish the pack had a few more for the price.
