USER GUIDE
Tangential entering by arc (recommended)
The tool enters the material in an arc movement.
At the end of the thread, the tool also extends in
an arc movement from the material. This method is
recommended because the cutter gradually enters the
material and the load on the tool increases gradually. THREAD MILLING TOOLS
