    Image of Product. Front orientation. Lathe Tool Insert Holders. 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.
