Cut off wheels for grinding welds

Last night I was working to get more grinding done on the quarter panel seams, a little over 6' of weld length done. Here's where the stainless rated cutoff wheels work so well. When I previously used the cheap discs (the brown cloud makers) this much weld would have taken well over two discs to grind, and an air hose to clean myself off before walking back in the house. One stainless rated disc did this amount, and diameter went from 3" to 2-1/2, so still have quite a bit left in it..

So despite how appealing those cheap cutoff wheels may be to those on a tight budget, cheap ain't always cheap. The stainless rated wheels are the only ones I buy anymore, money ahead.


Here's the weld grinding process...

Try using a 3" disc that has 1/4" wide by 1/2" deep v notches cut into it the perimeter and mount it on a 2" backer. Makes it very easy to see what you are doing.
 
My local welding supply carries them, and sells them by the package or by each.. If your local doesn't carry the exact brand, see what they do have in stainless rated...
 
^ Well look at that, apparently the company thinks they have improved on the original... hmm... I've looked for a superior alternative to the 3M Green Corps for a long time, and while I've found one or two, the availability always seems spotty. I'm going to keep my eyes open for local suppliers of these discs.
