Turning Lathe Tool Insert Holders

Secure carbide inserts inside these holders for stable turning. They’re also known as indexable insert holders. Select a holder that’s compatible with your insert by matching the insert style and inscribed circle diameter (IC). Right-hand holders move from right to left toward the lathe chuck, left-hand holders move from left to right away from the lathe chuck, and neutral holders can cut in either direction.
