About Straight Flute Hand Taps

Sometimes referred to as hand taps, straight-flute taps are suitable for general-purpose manual tapping operations with a tap wrench. They have straight flutes along the cutting edge and can be used to tap blind holes and through holes. As the tap is rotated into a hole to create threads, the chips move into the flutes but are not evacuated.

The most common choice for general purpose hand tapping applications, use these high speed steel taps in a variety of materials, including steel and nonferrous metals.
