Even though that box might have been "tiny", it will save you a bunch of time, money, and effort! I've owned a tapping head for a number of years, and before I finally broke down and purchased one, I would usually go through 2-3 taps per folder....breaking them no matter what I did. Now I wear taps out, but have never broken one with the tapping head. It literally takes more time and effort to drill the holes now than it does to tap them.
At first I used mine on the milling machine, but got tired of setting it up and taking to down when I needed the mill for other things. I went to Home Depot and purchased a Ryobi 10" drill press for less than $100, that is now dedicated to tapping operations.....
The tedious part for me when using it on the mill was setting up something for the reversing handle....
When I put it on the drill press, I also built a slotted bar that I clamped to the drill press column for the reversing handle....
They are pricey little things, and new collets for them (for using different sized taps) are just outrageous, but there is just nothing that beats them for building folders, or tapping a lot of small holes!
