I have searched fleabay and after careful deliberation (looking CLOSE at the photos of the cheapie wheels) I have noticed that the wheels have varying size holes in the center, which would have these things all out of balance, easy to fly to pieces in your face..
They also look pretty shabby on the construction. You can get 50 of them for less than $10 100 for less than $25 and the more I thought about it I decided that just ONE of the genuine Dremel brand wheels would outlast 5 or more of these *** wheels.
I use these a LOT in the shop, my favorite tool for shortening a bolt or screw, cutting off pieces of tubing, making tools or spacers, anything that needs a superb cutting tool in a limited space, etc..
The best deal I can find on genuine DREMEL wheels is from Zoro tools, you can order from them or from their ebay sales, but here's the ones you want, these are the GOOD ones:
