Aluminum oxide abrasive, tough, durable and long-lasting Use to sand wood, paint, metal, plastic, and drywall The UPC of the product is 051144090013. Abrasives Grading System Comparison Chart between CAMI and FEPA. We will have a new product in the next couple months that we are testing and seems really promising. Abrasives Grading System Comparison Chart between CAMI and FEPA. 3Ms distributors sell more into the industrial channel, but the product is out there. 3M has a weird distribution channel and the pricing would have been ok but a big commitment for a product that I didn't feel worked better than Abranet or not a whole lot better than the Mirka Gold we sell. CAMI (Silicon Carbide) (1600 grit FEPA) Blue (pad/sponge combo) Scotch-Brite is considered to be about 1000 grit CAMI (2000 grit FEPA). The FEPA value inside the parentheses is the equivalent.) 7448 - Light Grey, called Ultra Fine Hand - 800 grit. ANSI/ CAMI papers use a wider particle size distribution (centered on the mean size) than FEPA papers. (The CAMI grit value is directly from 3M. I also don't like that it only goes up to 320. There is a philosophical difference in the two systems. It performed worse on removing a film finish, like sanding off lacquer, which is a tough ask. On oily/sappy/wet wood, it loaded up bad and didn't clean up well (hitting it on a crepe pad). Some really liked it, others were not impressed. You can download a grit chart HEREĪfter seeing this, we got a bunch of Cubitron, cut it to 2" and 3" disks and sent it out to a bunch of people to test. You can read my comments on the YouTube video, which I posted 6 months ago, and have not been replied to. But they don't always state which system they use. Typically, European manufacturers use FEPA/P Grit and US manufacturers use CAMI, China, that's a bigger issue. So a 120 grit test would not really be fair because a FEPA/P grit 120 would have a 125 micron particle size and a CAMI would be somewhat smaller, but between 125 and 100 micron. But, it was also on kiln dried flat boards and I was never able to figure out what grit system 3M uses, ANSI or FEPA. I watched his video, and for the type of test, this is probably the most fair I have seen out them all.
