9 X 11 PREMIUM BLACK ZIRCONIA

I was skeptical about spending more on zirconia sheets, but the black grain cuts through oak way faster than the aluminum oxide I used before and barely dulls. The 9 x 11 size fits my quarter-sheet sander with just a bit of trimming.

Bought these for stripping old paint off a deck and they hold up way longer than the cheap sheets I used to grab. Only gripe is they clog a bit on softer woods, but a quick tap clears them. Solid for the price.

The zirconia grain really does cut faster than the aluminum oxide sheets I used before, especially on oak. Only gripe is the backing paper tears if you push too hard on a tight edge, but for the price it's solid.
