Here we are over 11 years after this video was made. Watching other videos of the Cubitron 2, I bought a box of 9"x36 grit Cubitron 2s. OMG !! Hang on to your grinder when you engage the steel. These things remove massive amounts of metal stock fast. They dont over heat the metal nor the will the disk over heat, even at the outer edge of the 9" size. An amazing product for removal when needed. If you want less removal, either get some finer grit, or use a flapper disk etc. But for large amounts of stock removal fast, the course grit Cubitron 2s are an amazing product. Thanks 3M.

"best ceramic fibre disc so far" Well good that you dont tell us what u compare... the test is useless this way. Also: There is a big variable in the pressure applied. I could make a video where i make any product look better than any other product just with the few detals you leave out of this video. Like said pressure or how worn the disc is (or a new one if it will perform better for some reason) You try to sell a premium product... why cant you (3M) make a premium video to show just _how_ much better the product is?
