When milling thread, screw interpolation is usually used to process thread. This cutting process makes the machining nominal straight

Multi tooth thread and single tooth thread with diameter of 1 mm or more become a reality.

Advantages:

– thread depth can be equal to drilling depth

– requires less torque than tap and thread roll forming

– short chip to avoid chip removal

– high speed cutting possible

– reliable process and longer processing life

A tool with only one tooth train must be used in the following cases:

– if there is not enough space at the bottom of the blind hole.

- if the cutting pressure is too high with the tool of two tooth rows.

– if the tool is also used for different slopes.
