Review on Home Tools for JEWELRY PRODUCTION Installation by Richard Gross

I bought these drill bits for plastic model making and DIY and will be using them with a Dremel Micro rotary tool. I don't need any additional collets. Drills are suitable for ordinary ones. With plastic models, I easily make holes of 0.1 mm, but pay attention to the rotation speed of the tool. With bits this small, you'd better use the lowest speed you can set or you might damage your bits.
