When tapping a hole, you will get a lip of material around the hole. To stop this from happening, use a single flute countersink and bore out (you can do this by hand with aluminum) a small bit around your hole. You can do this post tapping if you want, but then you have to run the tap through again to make sure you did not screw up the thread.
The Single Flute Countersink set is next door above all the taps. 82deg for english, 90deg for metric.
Also, MANIFOLD...I never really knew what the definition was exactly. Maybe because it has multiple ones:
For basics, a manifold is "something having many different parts or features".
In Machinery, manifold means "a chamber having several outlets through which a liquid or gas is distributed or gathered".
