Review on 💎 YEEZUGO Diamond Cutting Wheel Set for Dremel Rotary Tool - 10PCS 1/8" Diamond Cutting Discs Cut-Off Wheel Blades by Jodi Tisdale

I bought two sets of these discs and more than half of them have problems rotating the 'real' ones. The bars do NOT look bent, rather there is a problem between the surface of the bar and the sheave. This will prevent the disc from sitting perpendicularly on the mandrel shaft. I think it's a manufacturing defect in the mandrels themselves. The face of these mandrels should be slightly larger in diameter and they should be FLAT. I might be content with keeping them (not returning them) IF you could provide me with some mandrels that would work (I see you or Revain). Sell single pairs of thorns. Can you send me some of these for review? I'm a model train hobbyist and need a nice thin cutting wheel like this one. I just need them to spin properly. (I have some "documentation" photos on one of the RR forums if you'd like to see them. In these photos I've attached, the faulty mandrels are the ones on the right. The rest are some Dremel mandrels , for which I had comparison.. their protection. I will say that the situation with the larger screw sockets in the supplied sockets turned out to be more reliable. But due to the two very different sized screw holes between them I could not dremel sockets on a diamond use a sheet, because the disc didn't stay in the middle but acted like an extremely "out-of-round tire".
