I have a set just like this. The problem is that they simply don’t cut or grind anything. I’ve tried them on plastic and they simply refuse to remove material.
These usually aren’t good for plastic. They melt the plastic which instantly coats the diamond surface with a slick plastic coating, making it useless for grinding.
I found they do work ok on wood and metal.

I bought what appears to be this exact kit at a tool show about a year ago. Unfortunately the bits were pure junk with the diamond coating separating from the shaft with even the gentlest of uses. Tried running them at lower RPMs, same problem. Even tried using them with water running over them to keep them cooler, no difference. Might just have been a bad batch so YMMV but I’d probably not go there again personally.
