The standard hardware store has one kind of tap.

If you look in a machinists catalog there is a bewildering array of
taps.

So my question is something like?

Can someone give me the 5 min class in what kinds of taps are used for
what?


Do you use a different tap for
Aluminum?
Steel?
Plastic?


When do you use a 4 flute, when do you use a
tap with other than 4 flutes?

What is the strongest tap (aka one I won't snamp off)

Any taps with a leading guide pin that aligns with the hole for hand
tapping?


What is a roll tap?
