ZIRCONIA AIR FILE BELT

Had to swap out my old 80-grit belts for these zirconia ones, and the cut rate on stainless steel is noticeably faster with less heat buildup. The 180-grit finish is impressively smooth for a general-purpose abrasive.

Running these on my Dynabrade for some metal finishing projects, the 80-grit belt cut fast and held up way longer than the aluminum oxide ones I used before. The edges didn't fray, which was a nice surprise.

I wasn't sure about the zirconia-alumina material at first, but on my Dynabrade it cuts through metal fast and stays sharp for a long time. Even the 36 grit works aggressively without loading up, and the 180 finishes clean. Definitely buying more of these in different grits for my shop.
