Customer Reviews (4.8 / 5 · 5 reviews)

Matthew ★★★★★

The adhesive backing held firmly while I was polishing metal parts, even after cutting the sheet into narrow strips. The zirconia grain cut aggressively without loading up, making quick work of a rough edge.

Joshua O. ★★★★★

I cut these down to smaller strips for detail sanding, and the zirconia grain really holds up longer than standard aluminum oxide. The adhesive backing sticks firmly to my sanding block without peeling off mid-use.

Brian B. ★★★★★

The 16 1/2" length is perfect for cutting into custom strips, and the PSA backing grabs tight without any bubbling. I've burned through three sheets on a big sanding project and they're still cutting cleanly.
