External thread turning
This is the most common thread turning method. It is often easier
and less demanding on the tool and there are a number of different
methods which can be used to achieve the desired results.
Upside-down tool holders
In many operations, it is bene cial to use a tool holder in an
upside-down position, to help remove chips more effectively.
Drop-head tool holders are specially developed for threading
upside-down and allow the correct centre height to be maintained,
without having to change the clamping in the turret.
