For some minor grinding/sanding these should be fine. I was stripping rust and paint off of some metal and thought this would be a good cost savings rather than $9 for a single disc from the box stores. They wore through and became ineffective fairly fast, for my usage, and got 4x the life out of the one that i got from the box store.
