This does look like a neat tool for some limited applications. The pictures show sizes that would make a Whitworth fan swoon, but the specs only show a modest set of metric sizes. There doesn't seem to be much here for standard aircraft sizes. And if there were, I'd use it on 6-32 only under extreme duress.

Skeptical here, on the quality of the threads.

And what do you do if you are not doing a through-hole? The hole you drill with this would be twice as deep as the threaded part, wouldn't it?

Combination drill & taps have been around for quite a while. They work great in aluminum but steel is a bit more challenging. The whole set for $29 means they are made out of chinese magic metal. A 1/4 -20 size from MCS would be about$12 ea.
