Titanium Nitride Coating (TiN) increases surface hardness for longer tap life, and acts like a lubricant that won't squeeze out.

High Speed Steel, heat treated for long life
A good tap for stainless steel and other machinable materials.

Use a #68 drill as the tap drill for new holes in soft material with a depth of 2/3’s of the major diameter. You may need to go larger for a deeper hole or harder material.

HINT: Tapping small holes is very tricky. You may have to experiment with the tap drill size, depending on how deep you are tapping and the accuracy of your set-up. The difference between the root and the crest of the thread is pretty small. A little drill run out and you wind up with an over-sized hole and no threads. A dull drill or center drill may work-harden the part, making the tapping process more difficult.
