Keep chips clear while tapping. Also known as gun taps, these have spiral-point flutes that push chips ahead of the tap and out of through holes.

Clear chips while tapping deep and hard-to-reach holes. These taps have an extra-long shank for extended reach.

These taps are made of cobalt steel for higher strength and wear resistance than standard taps. Their flutes are designed to keep chips clear, so they don't need to be reversed to prevent buildup.
