This tool is very dangerous. I bought it about 1.5 years ago and haven't used it for any other project since. I didn't do it then, but today I decided to give it a try. I tried this on my drill press first BUT my drill is not deep enough for this due to the sides of the router bit resting against the drill press support/stand. I decided to use them with a regular hand drill BUT it was so unsafe it just nll jumped in place making my project completely confusing. I assume this is my fault as I should have done a test run on the other part first. I'll definitely throw it in the trash. It's so unsafe. Maybe the "intermediate" version works, but I wouldn't even waste my money or time trying to figure it out. If you use this on your drill press: WATCH YOUR FINGERS.
