Fits perfectly into my rotary tool. No deformation when rotated at high speeds and unlike other bits I have used, it drilled into the gold and silver fast and accurately without dulling immediately.

I used this for a project yesterday and aside from having a longer cord I don't think I'd change anything about it. I didn't use all the different bits but the ones I did use stayed in place well, it was easy to change them, and the power of the drill made them very effective. At first I thought maybe I would have liked variable speed since I'm cautious with my work but then I realized going slower probably wouldn't work as well so in the end I was glad about the power.
