Advent Tool and Manufacturing Inc.'s Octi-Edge threading and grooving system accepts inserts with up to eight cutting edges. It is made in the U.S.
The V 60-degree partial profile insert cuts without "topping" the OD of the thread. The same insert can be used for a range of different thread pitches.
The 60-degree full-profile insert cuts the complete thread profile, including the crest. For every thread standard and pitch, a separate insert is required.

threading
Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.
