I'm going to weigh in on the power tapping.... there are special taps made for speed tapping, and those make all the difference. The "normal" taps that come in a set from the hardware store ****! And you'll break them very quickly if you try to power tap with them.
The speed taps will push the chips forward, and can easily be used in a drill. These work best for thinner materials, but can also do thicker materials.
There are also thread forming taps for softer materials like aluminum, copper, etc. These don't cut the material, instead they deform and make the threads. These work very well in aluminum, as the material hardens slightly during the tapping process resulting in very clean threads. We have used these in high volume manufacturing, tapping thousands of holes. A good tap lubricant also helps immensely.
I personally use the forward cutting taps for all of the common tapping I need to do, 10-24, 1/4-20, 5/16-18, 3/8-16 and 1/2-13 along with a tapping fixture to get everything nice and square. This makes tapping so easy, and I can have my wife do the high volume tapping on projects. She actually enjoys this job the most, so that's bonus!
The forward cutting speed taps are easily available from Fastenal or MSC Direct, etc. Well worth it to buy!
