Insert clearance angles
Two types of angular clearance between the insert and thread are
necessary for precise, accurate threading. These are:
• Flank clearance
• Radial clearance

Cutting edge clearance between the sides of the insert and thread
 ank is essential to ensure that tool wear develops evenly, to give
consistent, high quality threads. The insert should therefore be
tilted to gain maximum symmetrical clearance from the  anks ( ank
clearance angle).
The tilt angle of the insert should be the same as the helix of the
thread, to ensure success.
