Leo M. ★★★★★ Oct 22, 2026

Finally, a 1/4 sheet that doesn't shred halfway through a project. The aluminum oxide cuts through the old paint I'm stripping without loading up, and the 4-1/2" x 5-1/2" size fits my sander like it was made for it. I've already ordered another pack of the finer grits.

The brown aluminum oxide cuts through old paint much faster than the garnet paper I was using before. Grit seems consistent across the sheet and it holds up well on my orbital sander.

The 4-1/2" x 5-1/2" size fits my palm sander perfectly, no trimming needed. Brown AO is holding up well on bare wood—no clogging after a whole drawer set.
