3M Cubitron II File Belt
Unfortunately it only lasts as long as other brands removing spot welds. The only real benefit it has is the belt is non directional where as the others I have tried are directional.

Used to grind down spot welds. Works great but don't get too carried away, they remove a lot of metal very quickly. They last quite awhile too.

Phenomenal
I always bought cheap belt for my belt sander and they cannot even last 2 spot weld. Those one are really great. They last a long run and they sand quick. They maybe costy to buy one shot but in the long run you will save in lieu of buying cheap one everytime. Fitted my princess auto powerfist 3/8 x 12-9/16

Best that I have used
These aren't inexpensive, but they do a way better job than similar ones sold at discount tool locations - Harbor Freight or Princess Auto.
