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.
