I bought this for a hobby project, wanting a clean hole in soda can aluminum, and this works perfectly. These drills make nice holes without dimpling the material. It took a while to get here, but it was worth the wait.Follow Up: After using this several times, I can see that there is room for improvement. The disc at the top doesn't spin well and it keeps unthreading the cap where the extra collet is stored. This should spin freely and smoothly. Other than that, it's done a great job.

Can't get it to keep drills tight! Garbage.

Item was as advertised ordered for my wife, has yet to be used.
