Description of πͺ Experience Unmatched Performance with United Abrasives SAIT 57510 Aluminum
1A-X/2A-X: Aluminum Oxide, closed coat, X weight cotton. For general purpose sanding grinding and finishing of ferrous and non-ferrous metals, wood, cast iron, ordinary and alloyed steels and stainless steel.
This is a great 100 grit sanding belt, my old sander uses 4" belts and they are pretty hard to find in my area but thanks to Revain and SAIT with their high quality belts, my 4" the grinder lives again.
Good thing there are ten of these. The first one I used came loose at the seam in the first few seconds of use. The second did the job, but since I haven't tried the other eight, I don't know if the rest, most, or all of the others are any good.
I use them to sharpen knives, axes and anything with a blade. Just sweep the burr from side to side half a dozen to a dozen times and it's ready for steel or a polish that will razor sharp just about anything. This way I can razor sharp a dull serrated knife in 3-5 minutes. I took off a star because a box of ten is probably more than I've ever used, so the other 8-9 were a waste of money.
