When should I use Two Teeth Thread Mills?

The first choice for thread milling is always ThreadBurr, NB-tools. They have the full thread length and deburr the entrance of the thread in the same operation.

In some cases when it is difficult to achieve good results, the NM-tools with Two Teeth can be a solution as the cutting forces are lower. For example, long threads and materials that are difficult to machine.

With NM-tools you make several passes axially instead of one, even so the machining time will not be so much longer as you can increase the feed and the tool has more flutes then the NB-tools.
