Madison ★★★★★

I’ve been using the 30-inch discs for heavy metal fabrication, and the zirconia grit holds up way longer than standard aluminum oxide on stainless steel. They load less than I expected, even under high pressure.

Zoe B. ★★★★★

I was skeptical about the 4" size for my detail sander, but the zirconia cloth cuts through old paint so fast I finished a whole door in half the usual time. The PSA backing held tight even when I got a bit aggressive on the edges. These discs will definitely last longer than the generic ones I've t

Zoe ★★★★☆

The 30-inch disc saved me a ton of time stripping paint off my metal shop door, but the adhesive backing could be a bit stickier for vertical work. Still, these discs cut fast and lasted through the whole project without wearing down.
