Triangle (T) turning inserts have three sides of equal length that form three cutting points with 60° nose angles. They're used for making longitudinal cuts, turning, facing, and chamfering in light roughing and finishing 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.
