If you look at their sanding belt page, and notice the Aluminum Oxide grinding belts (Item D); they are listed as 180, 320, 500, and 1200 grits on the website. When they arrived to me yesterday, I found to my surprise that they were labelled as Micron belts (Same product code on the bag), with a sheet showing the equivalent grit rating for the belts. I figure that they simply put up on the website what the grit would be for that particular belt, to make it easier for people to order what they wanted.

Good luck on your ordering; I'll be blowing some more cash on belts and some more honing compound myself. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
