Here is what I use a lot for #2 up to 1/4. I made these guys about 10 years ago now? Can't remember. I had to make a bunch of 1/4" hex pins for a fixture at work, so I ran off about a dozen more to make some custom tools like these, and some other extensions and special drill holders. The little pressed in round on the end was to take up slack in my drill/driver.
I used to have a little Hitachi 12v LiIon 1/4" hex drill/driver (not impact) that was amazing for power tapping. It would sometimes struggle with 1/4"-20's
, but it had a great clutch, and I power tapped many thousands of 4-40, and 6-32 holes with that thing without tap breakage. After over a decade of almost daily useage, the brushes finally burned out, and it's been sitting on the basement workbench for too long waiting to get fixed.
I have traditional tee handles, and other big tap wrenches, and use them as well, depending on the situation, and available clearance, but the "contraptions" above handle most hand tapping chores in the shop. I prefer to power tap whenever I can though. I sometimes have to drill and tap holes in weird places. Not shown is a right angle drive that has paid for itself time and time again too. The 1/4" drive system let's me get creative and get the job done.
I bought one of the import ratcheting tee handles a few years ago after using a guys good one at work. It's junk, and I gave it away. I don't like how far away the handle is from the business end, and the whole thing was a bit sloppy. The little palm ratchet above gives me great control and feel from the tap especially on the little stuff. The one in the origional post looks like a decent one though. I wouldn't waste my money on an import again.
I did stumble on this guy a while back, and may order it sometime. It looks handy for some bigger taps.

This reminds me, I need to make some more of those tap drivers for home use. As I build up the home shop more and more, I get frustrated at all the good tools I have at work, that I miss having at home.
