Unless you're tapping into unobtainium or something exotic, a standard HSS tap
is sufficent for the job. The key to using a tap or die is lubrication.
I prefer grease, as it will trap the chips and works better when working over-head.
However even oil will do the job. The other key, when it starts to bind, back it off a
half-turn, that will free the chips and allow the cutting surfaces to re-engage.
Unless you are setting up a machine shop, buy the taps individually, sets are a waste
of money. Pay only for the tap you need. Spend the savings on a quality tap handle,
instead and/or on extra of the correctly sized drill bits for starting the hole.
