Stop in for a cup of coffee

Holy crap, my friend just showed me these.

She said "could you ever use these" I said, heck yea.

She bought a set for her dad but he doesn't know how to use them because he is the kind of guy who might hurt himself with a pair of pliers.

Either way, I think this is a sweet idea

Asking too much from one tool I think. And if they were any good they should cost more than that -each.Maybe for aluminum, not steel. We use 2 flute 'gun taps' at work that are very strong and cut quick. Some have a drill tip, but I always pre drill.
And what ever you do, don't drive them with any tool other than a drill chuck. Those hex driver ends are pretty wobbly in a hex driver tool. One tool does all usually doesn't.
