A few months ago I bought a deburring wheel, $15 for an 8" X 1". Chinese?? No information other than it is marked #7. I assume that is the grit size. The 3M wheels were in the $65 range. I've got a really poor quality, variable speed bench grinder that allowed me to not exceed the Max RPM of the wheel. I removed the flimsy tool rest & hood, mounted the wheel and trued it with a piece of carbide. After some tests on various metals I'm happy with how it works. BUT it throws grit all over the place. So I fabricated a hood that has a pickup for the shop vac, much better.
How it works: sharp burs are wiped off in one quick motion at a diagonal to the wheel. Corners that need to be further eased are easily done, as the wheel is fairly aggressive. With a light touch a decent polish can be had. If just used for deburring I think the wheel would last a long time but when aggressively using it to soften shapes it wears relatively quickly. I'm going to order another one to have on hand.
