I thought I'd get lucky using these for 1/8" acrylic. The truth is I sometimes break them before I even use them. around them after 1 or 2 uses and after that they're not great. But that's more my stuff than anything. Otherwise these things are tiny as advertised and probably work great for their intended purpose. You get a lot of these and it helps I have them for mine Bought a Dremel but I had to take the paint ring off to fit (not an easy task).
