Round (R) Indexable Turning Inserts

260 products

Round (R) turning inserts have a circular shape with a continuous cutting edge. They have the strongest cutting edge of all the insert shapes for applications requiring high feed rates and high cutting force, but are more prone to vibration than other shapes. Round inserts are suitable for plunge turning, circular ramping, and rough turning. 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 section of the cutting edge when the old section 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.
