Review on 🔧 Sukeo Cut-off Wheel Screw Mandrel: 1/8 Inch Shank Holder for Rotary Tools (Pack of 12) - Efficient and Reliable by Cornelius Mosley

I've been using thin diamond coated cutting discs with Dremel tools for a long time. These mandrels have two shortcomings, both related to the screws: the diameter of the screw is too small for the thin diamond blade hole and cannot self-center. See photo. The right frame is on the left. On the right is the bad on this list. Notice how thin the screw is and too small to fit the hole in the cutting wheel. If you want to remove the rubber rings to really hold the wheel tight, the bolt is too long and you can't tighten it for metal-to-metal contact.
