Turning Carbide 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.

C-code holders secure inserts with a top clamp, leaving space for you to add a plate-type chipbreaker between the insert and the clamp.

Holders with an offset shank are good for reaching into tight corners and when working close to the chuck.
