Carbide Turning Inserts

Indexable turning inserts have multiple cutting edges and are used with lathes or CNC turning machines to size, shape, or add features to workpieces. They mount to compatible turning toolholders and can be rotated (indexed) to expose a fresh cutting edge when the old one dulls. They can be exchanged for new ones of the same style or a different style that's compatible with the toolholder without removing it from the machine. These inserts are differentiated by shape and cutting-point nose angle. Generally, inserts with fewer sides have small nose angles to reduce vibration and those with more sides have wide nose angles to increase cutting-edge strength. 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.
