Specialty turning inserts have nonstandard geometry, such as a specialized shape, side length, or nose angle. They install in specific toolholders used in custom turning applications. These indexable inserts mount to a compatible toolholder, which attaches to a lathe or CNC turning machine. They can be rotated (indexed) to expose a fresh cutting edge when the old one dulls. They can be replaced with new compatible inserts of the same style or a different style without removing the toolholder from the machine. Indexable turning tools require fewer tool changes than solid tools in high-volume metalworking and fabrication applications with high speeds, high feeds, and difficult-to-machine materials.
