The threaded part of a tap between the flutes is called?

Explanation:
The part that actually performs the cutting is the section of the tap where the thread ridges sit between the flutes. The flutes are gaps that provide clearance and let chips escape, but the material removal happens on the threaded ridges in this middle region—the cutting section. The shank is just the grip area, the tapered portion is the starting chamfer that helps begin the cut, and the threaded body can include areas that aren’t actively cutting. So, the name for the portion between the flutes that does the cutting is the cutting section.
