Nice. I’ve mostly used those wheels for removing coatings. If you are careful, you can get a satiny finish with them too. I’ve also tried them in ergonomic softening applications, but I tend to stick with dremel-to-paper for that.
BTW, I hate coated blades most of the time but I have a few I like. Some of my favorites are a “black wash” or worn coating. I’ll try to remember to grab an example in the near future.
