3/4 X 20 1/2 吋 EdgeCore 陶瓷氣動砂帶，10 件

These belts chew through aluminum way faster than the zirconia ones I used to run, and the 20 1/2 inch length fits my file sander perfectly. Ten in a pack means I’m not reordering every week, which is exactly what I needed for production work.

The ceramic grain runs noticeably cooler than the aluminum oxide belts I used before, which makes a real difference when I'm hogging off metal on a long pass. I've done about a dozen blades with the first belt and it still has plenty of bite left, so the ten-pack should last me a good while.

I used these on some pretty tough maple edges and the ceramic material really stays cool compared to aluminum oxide belts I've tried. Only gave four stars because the adhesive on a couple seems a bit weak near the splice.
