circular thread milling bodies for 3-tooth indexable inserts

Article number GZ311330

Machining of internal and/or external threads.

Product features and benefits:

For 3-tooth indexable insert.
Cross-dimensional.
Smooth and reliable operation thanks to carbide base.
Tool for all pitches.
The diameter of the end mill should be smaller than 2/3 respectively 3/4 of the thread diameter for internal threads.
For external threads the diameter of the end mill should be smaller than the thread diameter.
