It's a similar tool. Mine is electric, not air, and it is not made by Campbell Hausfeld. I can't speak specifically about the product in the suit.
The air grinder came with a 20-page instruction manual. The first half of the manual consists solely of safety warnings. Not until you get to the second half is the usage of the grinder discussed. Even then, the instructions are interrupted every three or four sentences with another warning.
The person at the store said that the the grinder could be used as a cut-off tool. He was wrong. The instructions specifically state not to do that. If you tried anyway, you'd find that a cut-off wheel can't be secured to the arbor, unless you come up with some unapproved method of doing that.
My regular glasses have polycarbonate lenses, and I wore a face shield over them. I was working in close quarters, and I have to tell that you that this is a freaky tool. A four-and-a-half inch grinding wheel turning 10,000 rpm a few inches away from your face and your carotid and femoral arteries will reinforce the notion that this is no time for kidding around.
